Find the circumference and the area of a circle that has a diameter of 8.4 meters.

The area of a circle with respect to its diameter is:

a=(πd^2)/4, we are told d=8.4 so

a=8.4^2π/4

a=17.64π m^2

a≈55.42 m^2  (to nearest hundredth of a square meter)

C=πd, again d=8.4m so

C=8.4π m

C≈26.39 m (to nearest hundredth of a meter)

Ibelieve 4mn because it’s like you’re combining them
