Q. V=34πr3The volume, V, of a sphere of radius, r, can be found with the given equation. Which of the following correctly shows the sphere's radius in terms of its volume?Choose 1 answer:(A) r=43πV31(B) r=34πV31(c) r=(4π3V)31(D) r=(3π4V)31
Write volume formula for sphere: Write down the given volume formula for a sphere.The volume of a sphere is given by the formula V=34πr3.
Solve formula for radius: Solve the formula for r (the radius).To find r in terms of V, we need to isolate r on one side of the equation. We start by multiplying both sides by 43 to cancel out the 34 on the right side.43V=πr3
Divide both sides by π: Divide both sides by π to isolate r3.(43V)/π=r3
Take cube root to solve for : Take the cube root of both sides to solve for .
Simplify expression for r: Simplify the expression for r. \newliner=(3V4π)13r = \left(\frac{3V}{4\pi}\right)^{\frac{1}{3}}r=(4π3V)31
Match expression with choices: Match the simplified expression for r r r with the given choices.\newlineThe correct expression that matches our result is (C) r=(3V4π)13 r = \left(\frac{3V}{4\pi}\right)^{\frac{1}{3}} r=(4π3V)31.
