Jim is painting the inside of a circular helicopter pad. how many cans of paint would he need if the pad is 50 feet across and each can of paint covers about 200 ft2.

Number of can needed to paint inside of the circular helicopter pad = 1

Step-by-step explanation:

The circular pad is given to be 50 feet across.

⇒ Circumference of the circular pad = 50 feet

⇒ 2π·r = 50

⇒ π·r = 25

⇒ r = 7.96 feet

Now, Area of the circular pad = π·r²

⇒ Area = 3.14 × 7.96²

⇒ Area = 198.96 square feet

Now, one can of paint covers 200 feet² area of the pad

Hence, 198 feet² area can also be painted by using one can.

Therefore, number of can needed to paint inside of the circular helicopter pad = 1
