How do I find the area of the circular racetrack?
BabaBlast [244]

Answer:

8483 ft²

Step-by-step explanation:

Subtract the area of the smaller circle from the area of the greater circle

Greater Circle area:

πr² = π × 140²

= 61583.2 ft²

Smaller Circle area:

= π × 130²

= 53099.8 ft²

Area of track:

61583.2 - 53099.8 = 8483.4ft²

= 8483ft² (to the nearest ft²)

if a questions asks to find the area of half of the circle would you do 3.14(pie) times r2(radius squared) times 1/2? and if no
Leya [2.2K]

Answer:

A=\dfrac{3.14r^2}{2}

Step-by-step explanation:

The area of a circle is given by :

A=\pi r^2

Where

r is the radius of the circle.

If we talk about the area of half of the circle, it means we have to half the area such that,

A=\dfrac{\pi r^2}{2}\\\\or\\\\A=\dfrac{3.14r^2}{2}

Hence, this is the required solution.
