Answer:
3.14 if it asks to use 3.14 for pi 2 if it does not ask to use 3.14.
Explanation:
A=1/2 times d
Substitute pi with 3.14 and diameter with two.
A= 1/2 3.14 times 2
A= 3.14
If it does not ask to use 3.14 for pi then the answer is 2
Answer: 5.14 cu in
1/2 (π × d) + d, where d is the diameter of the semi
Perimeter = 1/2 (3.14 x 2) + 2
= 1/2 * 6.28 + 2
= 3.14 + 2
