42/3=r- 1/3can anyone show me the steps on how to do this?

R=5

Step-by-step explanation:

So you are solving for R first. You want to turn 4 2/3 into an improper fraction to solve;

4 2/3 =R-1/3

14/3=R-1/3

add 1/3 to both sides to get R by itself.

15/3=R

wait! before you answer simplify 15/3= 5.

Add 1/3 to both sides to get R.

So, 4 2/3+1/3=R-1/3+1/3

5=R

Step-by-step explanation:

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
