If I drive 8.5 laps around a circular race track and during that drive I go 32 mi, what is the radius of the track? Round to two

Black_prince [1.1K]

Answer: The radius of the track = 0.64 mi

Step-by-step explanation:

Fr circular track , Total distance covered around it = (Number of laps) x (Circumference)

As per given,

32 mi = 8 x (Circumference)

Circumference = $\dfrac{32\ mi}{8}=4\ mi$

Also, Circumference = $2\pi r$ , where r= radius so,

$2\pi r=4\ mi\\\\\Rightarrow\ r=\dfrac{4}{2\pi}\\\\\Rightarrow\ r=\dfrac{2}{\pi}$

Put $\pi= 3.14$

$r=\dfrac{2}{3.14}\approx0.64\ mi$

Hence, the radius of the track = 0.64 mi

A circular plot with a 160 foot diameter is watered by a spray irrigation system. To the nearest square foot, what is the area t

Anuta_ua [19.1K]

A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.

Area of a circle: A = pi x r^2

r = 160 / 2 = 80

A = pi x 80^2

A = 6400pi / 2 = 3200pi

3200pi = 10053.0965

The area water is approximately 10,053 ft^2.

Hope this helps!! :)
