The volume of a hemisphere is 144 pi. Find the radius and total surface area.
sineoko [7]
Formula of the Volume of a hemisphere:
V = \frac{2}{3}\pir³
144\pi = \frac{2}{3}\pir³
Multiply by 3 to cancel fraction in the right side
144\pi × 3 = 2\pi r³
432 \pi = 2\pir³
Divide by 2\pi on either sides to isolate r³
\frac{432 \pi }{2 \pi } = \frac{2 \pi }{2 \pi }r³
2\pi and 2 \pi cancel out
216 = r³
Take cube root to find the radius
\sqrt[3]{216} = \sqrt[3]{r^3}
6 = r
Radius is 6 units

The formula of the surface area of a hemisphere is:
S.A = 2\pir² + \pir²
       = 2\pi(6)² + \pi(6)²
       =2\pi × 36 + 36\pi
       = 72\pi + 36\pi
       = 108\pi units²  (in terms of \pi)
       ≈ 339.12 units²

Surface area = 108\pi units
