There is a hemispherical bowl. A cone is tobe made such that, if it is filled with watertwice and the water poured in the bowl, itwill be filled just completely. State how willyou decide the radius and perpendicularheight of the cone. |
Answer» Answer :
Given :
To find :
Step-by-step explanation :Volume of hemisphere = 2/3 πR3 Volume of hemisphere = 2/3 πR3 Volume of cone = 1/3 πr2 × H By the given condition ; 2 × volume of cone = volume of hemisphere ∴ 2 × 1 / 3 πr2 h = 2 3 πR3 ∴ r2 h = R3 ∴ if, r = h = R Then both sides will be equal. ∴ if radius of base of the cone is R and its height is R, which is equal to radius of the bowl, then a cone satisfying the given condition can be made. |

Keeping the height same how many times the radius of given cyclinder should be made to get a cyclinder having double the volume of original cyclinder. |
Answer» Answer :Step-by-step explanation :Given :
First we USE the formula to find the volume of cylinder, Volume of cylinder ( V ) = πr²h keeping the HEIGHT same Now, Let the new radius be R Then, new Volume ( V') = πR²h also ( V ) = 2 (V') Volume of cylinder = Volume of new cylinder πr²h = 2πR²h r² = 2R² r = R√2
∴ the new radius should be √2 times the original radius . |

Show that x^a(b-c)÷x^b(a-c) ÷ (x^b÷x^a)^c = 1 ????? |
|
Answer» x^[a(b - c)] / x^[b(a - c)] } / (x^b / x^a)^c = 1 If so, then the first thing that I'll do is simplify the EXPONENTS. Distributive properties in the first TWO and the exponent of an exponent is the product of the exponents in the third: [ x^(ab - ac) / x^(ab - bc) ] / [x^(bc) / x^(ac)] = 1 Division of fractions is the same as the multiplication of the RECIPROCAL: [ x^(ab - ac) / x^(ab - bc) ] * [x^(ac) / x^(bc)] = 1 In each set of braces, the quotient of two numbers of the same base is the same as the differences in the exponents: x^[(ab - ac) - (ab - bc)] * [x^(ac - bc)] = 1 and simplify: x^(ab - ac - ab + bc) * x^(ac - bc) = 1 x^(-ac + bc) * x^(ac - bc) = 1 And finally, the product of two numbers of the same base is the same as the sum of the exponents: x^[(-ac + bc) + (ac - bc)] = 1 and simplify: x^(-ac + bc + ac - bc) = 1 x^(0) = 1 Anything to the 0 POWER is 1, so this is TRUE.
