1. What is the circumference of the circle in terms of pie?

2. What is the area of the circle shown in terms of pie?

1 = C = 2 x pi x r

2= D = pi x r^2

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
