Find the sum of measures of all interior angles of a polygon with number of sides 8

Step-by-step explanation:

Sum of measures of an interior angle of a polygon is given by

( n - 2) × 180

where n is the number of sides

From the question the number of sides is 8 so n = 8

The sum of it's interior angles is

(8 - 2) × 180

6 × 180

Hope this helps you

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
