Step-by-step explanation:
The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
Answer:
Step-by-step explanation:
The formula of a volume of a cylinder:
r - radius
H - height
We have the radius r = 12cm and the height H = 20cm. Substitute:
The formula of a volume of a cone:
r - radius
H - height
We have the radius r = 8cm and the volume V = 2880πcm³. Substitute:
