Question

Find the area of a circle with radius 4ft use the value 3.14 for pi and do not round your answer be sure to include the correct unit in your answer

Answer 1

Answer: The formula for the area of a circle is:

A = πr^2

where A is the area, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

In this case, the radius is given as 4ft. So, we can substitute r = 4ft and π = 3.14 in the formula to get:

A = 3.14 x (4ft)^2

A = 3.14 x 16ft^2

A = 50.24ft^2

Therefore, the area of the circle with radius 4ft is 50.24 square feet.
