Question

If the butcher paper is 21 inches long,what is the area of one circle

Answer 1

=
`12.25`
`\pi`

Explanation:

Given:

Length of butcher paper,(diameter of three congruent circle) = 21 inches

Means, diameter of a circle =
`(21)/(3)` = 7 inches

Questioned asked:

Area of one circle = ?

Solution:

Radius of a circle ,r = half of of one circle's diameter

r =
`(7)/(2)`

=
`3.5`

Area of circle =
`\pi`
`r^(2)`

`3.5*3.5`
`\pi`

=
`12.25`
`\pi`

Therefore, Area of one circle ==
`12.25`
`\pi`
