(2.7 × 109) (5.9 × 107) 2. ( 3.0 6.0 ) ( 109 107 ) 3. 0.5 × 102

1. (218) (631.3) = 185,791.59

2. i don't know if I have to multiply

3. 0.5 × 102 = 51

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

47 - 90 = 43

43 - 180 = x

x = 137
