Question

A flowerbeds around the base of a tree. It is enclosed by stones to form a circle that measures 25.12 feet around. What is the radius of the circle? Use 3.14 for Pi.

A.) 8.0 feet
B.) 4.0 feet
C.) 2.0 feet
D.) 12.0 feet

Answer 1

To find the radius of the circle, use the formula for the circumference of a circle: C = 2πr. Substitute the given circumference into the formula and solve for the radius to get the answer.

Step-by-step explanation:

To find the radius of the circle, we need to use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius.

We are given that the circumference of the circle is 25.12 feet, so we can substitute this value into the formula and solve for the radius:

25.12 = 2 * 3.14 * r

Dividing both sides of the equation by 2 * 3.14, we get:

r = 25.12 / (2 * 3.14) = 4

Therefore, the radius of the circle is 4 feet. Answer choice B is correct.
