<h3><u>Answer:</u></h3>
The circumference of a circle with diameter of 98 in. is about 308 in.
<h3><u>Step-by-step explanation:</u></h3><u>We know the diameter. Using the diameter, we can find the circumference.</u>
- => Diameter = 98 in.
- => Radius = 98/2
- => Radius = 49 in.
<u>Circumference = 2πr</u>
- => 2 x 22/7 x 49
- => 2 x 22 x 7
- => 308 in.
Therefore, the circumference of a circle with diameter of 98 in. is about 308 in.
