Question

A circle has a diameter of 10 centimeters. What is the area of the circle

Answer 1

Answer: 25
`\pi`

Step-by-step explanation:

The equation you use to find the area of a circle is:
`\pi r^(2)` where r is the radius of the circle. We know that a diameter is twice that of the radius. Therefore, we divide the diameter, 10, in half to find the radius, which ends up as 5. We can then input 5 into our equation (
`\pi 5^(2)`). Since it wants us to leave pi in our answer, we square 5, (5 × 5) to get 25. That is how you get 25
`\pi`.
