Answer:
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
