Question

PLEASE HELP!! IM VERY STUCK.

Although she's only in middle school, Tameka loves to drive go-carts! Her favorite place to drive go-carts, Drivers Delight, has 3 circular tracks. Track 1 has a radius of 60 feet. Track 2 has a radius of 85 feet. Track 3 has a radius of 110 feet.
a. Compute the circumference of Track 1.
b. Compute the circumference of Track 2.

Answer 1

Circumference of Track 1 is 377.14 feet and circumference of Track 2 is 534.29 feet.

Explanation:

Consider the provided information.

Drivers Delight, has 3 circular tracks. Track 1 has a radius of 60 feet. Track 2 has a radius of 85 feet. Track 3 has a radius of 110 feet.

Part (A)

Compute the circumference of Track 1.

Track 1 has a radius of 60 feet.

The formula used to find the circumference of the circle is:
`2\pi r`

The circumference of Track 1 is:

`2\pi r=2* (22)/(7)* 60`

`2\pi r=377.14`

Thus, circumference of Track 1 is 377.14 feet.

Part (B)

Compute the circumference of Track 2.

Track 2 has a radius of 85 feet.

The circumference of Track 2 is:

`2\pi r=2* (22)/(7)* 85`

`2\pi r=534.29`

Thus, circumference of Track 2 is 534.29 feet.

Answer 2

There is only one useful equation that we can apply to both questions. That would be the formula for the circumference of a circle.

Circumference = 2πr, where r is the radius of the circle

a.) Since track 1 has a radius of 60 ft,

Circumference = 2π(60 ft) = 378 ft

b.) Since track 2 has a radius of 85 ft,

Circumference = 2π(85 ft) = 534 ft
