Formula: SA = 2πr² + 2πrh
h =40 in
Diameter d =12 in.
Radius = r = d/2 = 12/2 = 6 in

SA = 2π6² + 2π*6*40 = 72π + 480π = 552π (in²)

SA = 552π = 552*3.14 = 1733.28 (in²)
Answer: 1733.28.

Evaluate 4 square root 9 square root 9 over 4 square root 9^5

Sedbober [7]

$\frac{\sqrt[4]{9}.\sqrt{9}}{\sqrt[4]{9^5}}$

$\frac{9^\frac{1}{4}.9^\frac{1}{2}}{9^\frac{5}{4}}$

$\frac{9^\frac{6}{8}}{9^\frac{5}{4}}$

$9^{\frac{6}{8}-\frac{5}{4}}$

$9^\frac{-1}{2}$
