Question

Calculate the amount of space a rug with a diameter of 3 feet will take up in Maria’s room use 3.14 for pi

Answer 1

7.065 square feet

Explanation:

area =
`\pi` *
`(radius)^(2)`

since diameter is given, we have to find radius

D= 3

r= 3/2

=1.5

substitute this value in the formula

area = 3.14 *
`(1.5)^(2)`

= 3.14 * 2.25

= 7.065 square feet

Answer 2

7.065 square feet

Explanation:

To calculate the area of a rug with a diameter of 3 feet, we can use the formula for the area of a circle:

`\sf \textsf{Area} = \pi * \left( \frac{\textsf{Diameter}}{2} \right)^2`

Given that the diameter (
`\sf D`) is 3 feet, substitute this value into the formula and use
`\sf 3.14` for
`\sf \pi`:

`\sf \textsf{Area} = 3.14 * \left( (3)/(2) \right)^2`

`\sf \textsf{Area} = 3.14 * \left( (9)/(4) \right)`

`\sf \textsf{Area} = 3.14 * 2.25`

`\sf \textsf{Area} = 7.065 \, \textsf{square feet}`

So, a rug with a diameter of 3 feet will take up approximately 7.065 square feet of space in Maria's room.
