Question

Find the circumference and area of a circle with a

diameter of 26 meters. Leave your answers in terms of it

Answer 1

The circumference of a circle with a diameter of 26 meters is

C =
`26\pi`

The area of a circle is
`A = \pi (13)^2` =
`169\pi`

Explanation:

The circumference of a circle having radius 'r' is

C =
`2\pi r`

The diameter of a circle is passes through the center so d =
`2r`

`C = \pi d`

C =
`26\pi`

The area of a circle is A =
`\pi (r)^2`

`A = \pi ((26)/(2))^2`

`A = \pi (169)`
