Answer:

C = πd

The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius.

If a circle has a radius of 4, its area is 3.14*4*4=50.24.

If you know the diameter, the radius is 1/2 as large.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

0.0015 quart of paint to cover 1 square inch.

Let the area of the rectangle be 10000 in², hence:

Amount of paint = 0.0015 quart per in² * 1000 in² = 15 quart

Cost of paint = $2.75 per quart *  15 quart = $41.25

The total amount of paint needed is 15 quart and it cost $41.25.
