The volume of a cylinder is equal to h*pi*r^2 where h is height and r is radius. We are given everything we need to solve for the radius.
176pi = 11pi * r^2
176 = 11r^2
176/11 = r^2
r = sqrt(176/11) = 4 cm

Answer:
<h2>f(-6) = -33, f(4) = 7</h2>
Step-by-step explanation:
f(-6), f(4)
Put x = -6 and x = 4 to the equation of the function:
J=2l
j+l=240
sub 2l for j
2l+l=240
3l=240
divide both sides by 3
l=80
sub
j=2l
j=2(80)
j=160
