If the glass container has a height of 6.2 inches, what is its radius?
Answer
1.8 inches
2.1 inches
3.1 inches
3.6 inches

Answer 1

V = pi*h*r^2

252.3 = 6.2pi *r^2

r = sqrt(252.3/6.2pi)

Answer 2

so would the answer be 3.1 ? im so confused

Answer 3

that expression is the radius, put it in a calculator to find out the decimal answer

Answer 4

so i divide 252.3 by 6.2?

Answer 5

252.3/(6.2*pi)

Answer 6

and i got 12.9

Answer 7

what should you do next?

Answer 8

divide it by 2?
