Answer 1

Answer:

i believe the answer is 74.6

Step-by-step explanation:

when you find the area of a circle (with diameter), you multiply 1/4, times pi (3.14), times diameter squared.

work:

1/4 x 3.14 x 9.75^2

= 74.6240625, rounded to the nearest tenth:

=74.6

hope this helps! :D

Answer 2

Answer:

74.7 in²

Step-by-step explanation:

1. The formula for the finding the area of a circle is πr²
2. Divide the diameter to get the radius:  9.75/2=4.875
3. Plug in 4.875 into r to get 3.14*4.875²= 74.6619129
4. Round up to the nearest 10th to get 74.7in²
