What is the equation of the circle with center (3.2, -2.1) and radius 4.3?
o a. (x+ 2.1)2 + (y - 3.2)2 = 8.6
o b. (x-3.2)2 + (x+ 2.1)2 = (4.3)2
o
c. (x+ 3.2)2 + (y-2.1)2 = 4.3
o
d. (x-2.1)2-(y + 3.2)2 = (4.3)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
