Question

25 POINTS PLS HELPPP WITH MATH

Answer 1

1) 23.55 inches

2) 102.36 mm

Explanation:

C = pi × d

1) C = 3.14 × 7.5

= 23.55

C = 2 × pi × r

2) C = 2 × 3.14 × 16.3

= 102.364 mm

Answer 2

1. 23.55 in

2. 102.36 mm

Explanation:

The circumference of a circle is calculated by the formula:
`C=\pi d=2\pi r` , where d is the diameter and r is the radius.

We can use this to answer both problems.

1. Since the diameter is 7.5 inches, then d = 7.5. Substitute this into the equation:
`C=\pi *7.5=3.14*7.5=23.55`. So, the circumference is 23.55 inches.

2. Here, the radius is 16.3 mm, so r = 16.3. Substitute this into the equation:
`C=2\pi r=2*3.14*16.3=102.364=102.36`. So, the circumference is 102.36 mm.

Hope this helps!
