Answer:
C. 570.20 ft²
Step-by-step explanation:
Surface
A = 2·pi·r^2 + 2·pi·r·h
A = 2·pi·5.5^2 + 2·pi·5.5·11 = 570.20 ft²
6 because if you add the negative 8 (it would become a positive 8) to the other side (to negative 2) then it equals 6 I hope that makes sense
= -2

To cover the toy box 35.475 sq ft paint is needed.
Step-by-step explanation:
Given,
The length (l) of the toy box = 3.8 ft
Width (w) = 2.65 ft
Height (h) = 2.75 ft
To find the amount of paint is need we need to find the lateral surface area first.
Formula
Lateral surface of the box = 2(l+w)×h
Now,
The surface area of the box = 2(3.8+2.65)×2.75 sq ft
= 35.475 sq ft
