The radius of a circle is 13 feet. What is the circle's area?
r=13 ft
Use 3.14 for 𝜋.
The formula for the area of a circle is A=𝜋r², where A is the area and r is the radius.
Substituting the given value for r into the formula, we get:
A = 3.14 x 13²
A = 3.14 x 169
A = 530.86
Therefore, the area of the circle is approximately 530.86 square feet.
To find the area of a circle, you can use the formula: A = πr^2.
Given that the radius (r) of the circle is 13 ft and π is approximately 3.14, we can substitute these values into the formula.
A = 3.14 * (13 ft)^2
A = 3.14 * (169 ft^2)
A ≈ 530.66 square ft
Therefore, the area of the circle is approximately 530.66 square feet.
