Question

The area of a circle with a diameter of 5cm

Answer 1

78.5 square inches is the anser for your question

Answer 2

19.625 cm² is your answer

Explanation:

Area of the circle can be solved using the equation: Area =
`\pi r^2\\`

Solve for r (radius). To find radius, use Radius =
`(diameter)/(2)`

Solve for radius

`(5)/(2) = 2.5\\`

Plug in 2.5 for radius. Remember that Area =
`\pi r^2\\`

Area =
`\pi 2.5^2\\`

Simplify

Area =
`\pi 6.25\\`

Area =
`\((3.14)(6.25)\\`

Multiply

Area =
`\ 19.625\\`

19.625 cm² is your answer
