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 |

Determine if it is possible to draw ∆PQR with side PQ=11cm,QR=5cm,PR=5cm |
|
Answer» ong>Answer: In a TRIANGLE PQR, PQ =8cm and QR= 7CM. The area of the triangle is 17cm^ 2. Calculate the two possible values of Area of PQR = (PQ*QR/2)*sin PQR, or 17 = (8*7/2)*sin PQR, or sin PQR = 17*2/(8*7) = 0.607142857, or We can find PR^2 = PQ^2+QR^2–2*PQ*QR cos PQR = 8^2+7^2–2*8*7*cos 37.38319842 = 64+49–112*0.794592695 = 113–88.99438184 = 24.00561816, or PR = 4.899552853 cm Area of PQR = 17 = (QR*QR/2)*sin PRQ =(7*4.899552853/2)*sin PRQ, or sin PRQ = 17/(7*4.899552853/2) = 0.991344108 Another value of |

Find the following products(y+8)(y-4)? |
|
Answer» ONG>Answer: Step-by-step explanation: ANSWERING using the Distributive Property ( O I L )
= ( y − 2 ) ( y + )
First Term, = ( y − 2 ) ( y + 4 )
Outer Term, = ( y − 2 ) ( y + 4 ) Inner Term, = ( y − 2 ) ( y + 4 )
LAST Term, = ( y − 2 ) ( y + 4 )
First Term, y and y
= y ⋅ y = y ²
Outer Term, y and 4
= y ⋅ 4 = 4 y
Inner Term, − 2 and y
= − 2 ⋅ y = − 2 y
Last Term, − 2 and + 4
= − 2 ⋅ 4 = − 8
Plugging all the answers, we get:
= y ² + 4 y − 2 y − 8
always simplify the answer by combining (adding) like terms, the like term is the 4 y and − 2 y , we get 4 y + ( − 2 y ) = 2 y
so the final answer is,
= y ² + 2 y − 8
