Question

Find the circumference of a circle with a diameter of 80 yards

Answer 1

251.3 yards (approximately)

Explanation:

We know that

C = π × d

C = π × 80 yards

In calculator, we put that in, and the approximate result is

251.3 yards

Hope it helped!

Answer 2

Answer: C = 251.3 yards

Big idea:

The formula for the circumference is
`\sf{C=\pi d}`.

Step-by-step solution:

First, write down what we know.

• diameter = 80 yards

We can now use the formula. Put in the values:

`C=\pi*80`

`C=251.3\:yards}` {circumference}
