For the rectangular parking area of the shopping center shown, which one of the following equations says that the area is 30,000 yd^2? a. x+(3x+100)=30,000 b. x(3x+100)=30,000 c. 2x+2(3x+100)=30,000 d. none of the above equation __ says that the area is 30,000 yd^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
