Chase plays the piano and the cello. for every 2 hours he practices the piano, he practices the cello for 3 hours. if he practiced the piano for 6 hours last week, how many hours did he spend practicing the cello?

if Chase practices 3hr of cello per every 2hrs of piano, first find how may times does 2hrs goes into the total 6hrs:

6 ÷ 2 = 3

Then multiply the number the hours of cello by the total 2 hours of 6;

3 × 3 = 9

so your final answer would be:  9 hours of cello

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
