Question

what is th best approximation for the area of a circle with a diameter of 13 meters use 3.14 to approximate pi

Answer 1

Hi! :)

So the formula to find the area of a circle is A=
`\pi`
`r^(2)`. The r stands for radius, so just a little simple math should give us your answer.

Following the rules of PEMDAS, you need to deal with exponents first. So
`13^(2)`=169. Then multiply
`\pi` by 169 and we should have our answer.

3.14*169=530.66

So your answer should be approximately 530.

Hope this helps!

Answer 2

The area of a circle is A=pi(r)^2. Since the diameter is 13, the radius would be 6.5. Doing the formula (3.14)(6.5)^2, the answer would be 132.665.
