I WILL MARK BRAINLIEST! I NEED HELP ASAP!!! Use the 3D solid below to answer questions #7a-c. 7a- Find the volume of the cylinder
7b- Find the volume of the cone
7c- Find the total volume of the solid

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

i found two solutions,   n = 2 • ± √3 = ± 3.4641
