Question

If the diameter of a semi circle is 2 inches what is the semi circles perimeter

Answer 1

Answer: 5.14 cu in

Step-by-step explanation:

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

Answer 2

Answer:

3.14 if it asks to use 3.14 for pi 2$\pi$ if it does not ask to use 3.14.

Step-by-step explanation:

A=1/2 $\pi$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$\pi$
