Question

HELP PLEASE!! An artist is drawing three large circles on the ground with diameters of 6m, 10m, and 13m. Identify the area of each circle rounded to the nearest tenth of a meter.

Answer 1

`A1=28.3\ m^(2)`,
`A2=78.5\ m^(2)`,
`A3=132.7\ m^(2)`

Explanation:

we know that

The area of a circle is equal to

`A=\pi r^(2)`

Part 1) Find the area of the circle with diameter 6 m

we have

`r=6/2=3\ m` -----> the radius is half the diameter

substitute the values

`A1=(3.14)(3)^(2)=28.3\ m^(2)`

Part 2) Find the area of the circle with diameter 10 m

we have

`r=10/2=5\ m` -----> the radius is half the diameter

substitute the values

`A2=(3.14)(5)^(2)=78.5\ m^(2)`

Part 3) Find the area of the circle with diameter 13 m

we have

`r=13/2=6.5\ m` -----> the radius is half the diameter

substitute the values

`A3=(3.14)(6.5)^(2)=132.7\ m^(2)`
