Calculate the area of a circular patio that has a radius r=3 yd. Use 3.14
A = pi * r^2
Substitute 3 for r.
28.26 yd squared
Right.
To calculate the area of a circular patio, we can use the formula for the area of a circle, which is A = πr^2, where A represents the area and r represents the radius.
In this case, the radius (r) is given as 3 yards and we are asked to use the approximate value of π as 3.14.
To find the area, we will substitute the given values into the formula:
A = 3.14 * (3)^2
A = 3.14 * 9
A ≈ 28.26 square yards
Therefore, the area of the circular patio is approximately 28.26 square yards.
