Question

The circumference of the circle is 87.92 cm. What is the diameter? (Use 3.14 for .)

Answer 1

Answer: The diameter is 28cm

Explanation:

Circumference is
`2\pi r` where r is the radius or just
`\pi d` where d is the diameter. For this, we'll use the one with the diameter.

`87.92=3.14d\\(87.92)/(3.14) =(3.14d)/(3.14) \\28=d`
