Question

25 points no I need help with math

Answer 1

1. 23.55 inches

2. 102.36 millimeters

Explanation:

1. Circumference = pi × d

3.14 × 7.5

= 23.55 in

2. Circumference = 2pi × r

2 × 3.15 × 16.3 = 102.364 mm

Answer 2

1. 23.55 in

2. 102.36 mm

Explanation:

First, the circumference of a circle is written as:
`C=\pi d=2\pi r`, where either equivalence works and d = diameter and r = radius.

1. We know that d = 7.5, so we just plug this into the equation:

`C=\pi *7.5=3.14*7.5=23.55`

Thus, the circumference is 23.55 inches.

2. We know here that r = 16.3, so we can plug this into the other equivalence:

`C=2*\pi *16.3=2*3.14*16.3=102.364` ≈
`102.36`

Thus, the circumference is 102.36 millimeters.

Hope this helps!
