The diagonal of a TV is 28 inches long. Assuming that this diagonal forms a pair of 30-60-90 righl triangles, what are the exact length and width of the TV?
A. 14,2 inches by 14.2 inches
B. 56 inches by 56,3 inches
C. 14 inches by 143 inches
D. 56/2 inches by 562 inches

The answer to your question is 414.48 ft²

Step-by-step explanation:

Data

height = 6 ft

diameter = 1 ft

# of fence posts = 12

amount of paint = ?

Formula

Area of a cylinder = πr² + 2πrh

Process

1.- Find the area of 1 cylinder

Area = (3.14 x 0.5) + (2 x 3.14 x 0.5 x 6)

Area = 15.7 + 18.84

Area = 34.54 ft²

2.- Calculate the area of 12 fencepost

Total area = 12 x 34.54

                = 414.48 ft²
