Diamond measured the base of a soda can and the diameter was 4 inches. What is the circumference of the bottom of the can? a
.9 inches
b
25.1 inches
c
12.6 inches
d
50.2 inches

c 12.6 inches

Step-by-step explanation:

radius = diameter/2 =4/2 =2 inches

circumference = 2πr

= 2× 22/7 × 2 = 12.6 inches

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
