The area A of a sector of a circle with radius r and central angle θ, where θ is measured in radians, is given by the formula . A = r2θ A = 1/2πr2θ A = πr2 A = 1/2r2θ A = 1/2πr2

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
