Apex Learning Study 4.2.1 What units do you use to report the area of a circle with a radius of 50 feet?

Step-by-step explanation:

Area of anything is allways reported in square units. Usually that is square of given unit because it's the simplest way:

R = 50 ft

A = πR² = π•(50 ft)² = π • 50 ft • 50 ft = 2500π ft² ≈ 7854 ft²

{Of course you can re-calculate the units, ex.:

3 feet = 1 yard so 50 ft = 50/3 yd then

A = πR² = π•(50/3 yd)² = π • 50/3 yd • 50/3 yd = 2500/9 π yd² ≈ 872.7 yd² }

the first one, all those points on the line just make a strait line.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
