Given V = 1/3pi(r^2)h, solve for r.

Dmitry [639]

Volume = (PI * r^2 * h) / 3

r^2 = (3 * Volume) / (PI * h)

r = Square Root (3 * Volume) / (PI * h)

Xsquared+11x+28+xsquared+13x+40

UNO [17]

X² + 11x + 28 + x² + 13x + 40

combine like terms

x² + x² = 2x²
11x + 13x = 24x
28 + 40 = 68

2x² + 24x + 68 is your answer

if you want it simplified:

2(x² + 12x + 34)

hope this helps
