Answer:

Step-by-step explanation:

Surface area: A = 4πr². If r = 9 in, then the surface area is

4(3.14)(9 in)² = 1018 in²

Volume: (4/3)πr³. Here, V = (4/3)(3.14)(9 in)³ = 3052 in³

Answer:

Volume-- 3053.6

Surface Area- 1017.88

Step-by-step explanation:

A=4πr2=4·π·92≈1017.87602

V=4

3πr3=4

3·π·93≈3053.62806

Use the quadratic formula with a = 2, b = -5, and c = 1

x = -b ± sq rt b2 - 4ac
-------------------- <---------- Please note: sq rt is over entire expression of b^2 - 4ac
2a

x = - (-5) ± sq rt (-5)2 + 4(2)(1)
-------------------------------- <---------Please note: sq rt is over entire expression (-5)2 + 4(2)(1)
2(2)

x = 5 ± √17
---------
4

x = 5 + 1√17 OR x = 5 + -1√17
