Answer:

0.314 gallon is required to cover a circular region with a radius of 40 feet

Step-by-step explanation:

Given

a gallon of paint will cover about 400 square feet in a single coat

To Find:

Number of gallons  required to cover a circular region with a radius of 40 feet = ?

Solution:

Step 1: Finding Area of the circular region

The  area of the circular region, A  = \pi r^2

where r is the radius

Now substituting r =  40 , we get

A = \pi \times 40

A = 125.6 ft^2

Step 2: Finding the number of gallons of paint required

To cover 400 sq feet  = 1 gallon

so to cover 1 square feet  = \frac{1}{400}gallon

Now to cover 125.6 ft we need

125.6 \times \frac{1}{400}

\frac{125.6}{400}

=> 0.314 gallon
