Simplify

b + 4 + 4 + b=

b + 4 + 4 + b=

= +b +b +4 +4

= 2b + 8

another way

b + 4 + 4 + b=

= +b +b +4 +4

= 2b + 8

= b =

= b= 4

Ans: b= 4

the answer is a reflection across the line m

step-by-step explanation:

on edge

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 !
