Nvm it is d
find the surface area of the cylinder with a radius of 9 inches and a height of 11 inches in terms of pi
a) 198 pi in^2
b) 234 pi in^2
c) 846 pi in^2
d) 360 pi in^2

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
