Tyson is creating a scale drawing of the area of his school. the rectangular drawing shows the length as 20 inches and the width

Brilliant_brown [7]

If 1 inch is equal to 3 feet so you can say:
20 inches are equal to 20*3 = 60
and 19 inches is equal to 19*3 = 57
and because the school is rectangular so the area of the school is:
60* 57 = 3420 :))
i hope this is helpful

Suppose the radius of a circle is 8. What is its area?

monitta

The Formula to find the Area of a circle using the radius is:
$A = \pi r^2$

r = 8
So:
$A = \pi r^2$
$A = \pi 8^2$
$A = \pi64$

And you get about 201.06193

So, the area of a circle with a radius of 8 is about 201.06

Hope this Helps :)
