PAGE:DATE1Find the base diameter af a cylinderwhose lateral surface area is 132 cm square and Height is 7cm |
Answer» Given:A cylinder WHOSE lateral surface area is 132 cm square and Height is 7cm To find:The base diameter Solution:We know the formula as: where "r" → radius of the base of the cylinder "h" → height of the cylinder But, L.S.A. of the cylinder = 132 cm² (given) ∴ substituting h = 7 cm
∴ Base diameter, d = 2 × r = 2 × 3 = 6 cm Thus, the base diameter of a cylinder is → 6 cm. ---------------------------------------------------------------------------------------- ALSO View:Find the volume of a cylinder where the area of its base is 45 CM square and height 9 CM The CURVED surface area of cylinder is 6160 cm square and the CIRCUMFERENCE of the base is 176 cm find the volume of the cylinder Find the curved surface area of a cylinder of radius 21cm and height 28cm? The volume and curved surface area of a cylinder are equal numerically. If the height is 7/2 times the radius of the base, find the radius |

Prove that if sina + cosa =2 then prove that sin⁴A+cosec⁴A =2PLS I NEED THE ANSWER QUICKLY . FIRST ONE TO ANSWER WILL BE MARKED BRAINLIEST |
|
Answer» it seems that the question has a flaw instead of it should be sin a + cosec a = 2 I am PROCEEDING to SOLVE taking this as correct sin a + cosec a = 2 SQUARING both side (sin a + cosec a )^2 = 2^2 sin^2 a + cosec^2 a + 2 sin a cosec a = 4 sin^2 a + cosec ^2 a + 2 sin a * 1/ sin a = 4 sin^2 a + cosec ^2 a + 2 = 4 sin^2 a + cosec ^2 a = 4 - 2 sin^2 a + cosec ^2 a = 2 again squaring both side (sin^2 a + cosec^2 a )^2 = 2^2 (sin^2 a)^2 + (cosec^2 a)^2 + 2 sin^2 a cosec^2 a = 2^2 sin^4 a + cosec^4 a + 2 = 4 sin^4 a + cosec^4 a = 4 - 2 sin^4 a + cosec ^2 a = 2 proved |

42. Find the ratio in which the line x - 3y = 0 divides the line segment joining thepoints (-2,-5) and (6, 3). Find the co-ordinates of the point of intersection.HOTS |
|
Answer» Solution :- Let us assume that, the given line x - 3Y = 0 intersect the line segment JOINING A(-2, -5) and B(6, 3) in the ratio k : 1 at point P(x,y). Now the section formula says that, the point which divides the line joining two points (a ,b) and (c , d) in the ratio m : n is :- P(x , y) = (cm + an)/(m + n) , (dm + bn)/(m + n) . So, Putting values now, we get :- → Coordinates of P(x, y) = (6k - 2)/(k+1), (3k - 5)/(k+1) Now, we have also given that, P lies on x - 3y = 0 . → x = 3y Or, → (6k - 2)/(k + 1) = 3{(3k - 5)/(k + 1)} (k + 1) will be cancel from both denominators,, → 6k - 2 = 9k - 15 → 9k - 6k = 15 - 2 → 3k = 13 → k = (13/3) Therefore, → Required Ratio = k : 1 = (13/3) : 1 = 13 : 3 Now, → Coordinates of P(x, y) = (6k - 2)/(k+1), (3k - 5)/(k+1) Putting VALUE of k = (13/3) , we get, → x = { 6*(13/3) - 2 } / (13/3 + 1) → x = ( 26 - 2 ) / {(13 + 3) / 3} → x = 24 * 3 / 16 → x = (3 * 3)/2 → x = (9/2) and, → y = { 3*(13/3) - 5 } / (13/3 + 1) → y = ( 13 - 5 ) / {(13 + 3) / 3} → y = 8 * 3 / 16 → y = (3/2) Hence, Coordinates of P are (9/2, 3/2) .Learn More :- PROVE that the mid point of the line joining points (-5,12) and (-1,12) is a point of trisection of the line joining the... in what ratio is tge line joining the points (9, 2) and (-3, - 2 ) divided by the y axis? also find the coordinate of th... find the equation of the straight line which passes through the point 4,3 and parallel to line 3x +4y=7 |

|
Answer» Given :- Which GIVES the best estimate and the exact product of (5.9)(8.28) ? A) estimate: 40; exact product: 48.852 B) estimate: 48; exact product: 48.852 C) estimate: 400; exact product: 488.52 D) estimate: 480; exact product: 488.52 . Solution :- we know that, :- When rounding to the nearest hundred, look at the tens DIGIT of the number. If that digit is 0, 1, 2, 3, or 4, you will round down to the previous hundred. { The hundreds digit does not CHANGE.} If that digit is 5, 6, 7, 8, or 9, you will round up to the NEXT hundred. { The hundreds digit increases by one.} All rest digits changes into 0. So, → Estimate value of 5.9 = 6 → Estimate value of 8.28 = 8 Than, → Estimate product = 6 * 8 = 48. and, → Exact value = 5.9 → Exact value = 8.28 Than, → Exact product = 5.9 * 8.28 = 48.852 . Hence, Option (B) is correct . estimate: 48; exact product: 48.852. Learn more :- 57.63 : 3 is the. Place Product of digit in the TENTHS place and thousandths place of 15.246 |
