Question

Please help me!! Find the area of the circle:)

Answer 1

2.46

Explanation:

Answer 2

`A=283.528736986`

Explanation:

The formula for the area of a circle is:


`A=\pi * r^2`

Remember that the radius is half the diameter, we are given the diameter which is 19, which means we need to find the radius:


`d=19`

`19*(1)/(2) =9.5`

`r=9.5`

Substitute and solve:


`A=\pi *9.5^2`

`9.5^2=9.5*9.5=90.25`

`\pi *90.25=283.528736986`

`A=283.528736986`

Since the question doesn't say to round the area is "283.528736986."

Hope this helps.
