1) 12in
<em>
Step-by-step explanation:
</em>
The circumference is 75, so to find the diameter you have to divide 75 by 3.14. You get 24 approximately. Then divide the diameter by 2, so 24/2=12.
Your error: pi is 3.14 not 3.24
Answer:11.9 inches
Step-by-step explanation:
Circumference(c)=75inches
Pi=3.14
Circumference(c)=2 x π x radius(r)
75=2 x 3.14 x r
75=6.28 x r
Divide both sides by 6.28
75 ➗ 6.28=(6.28 x r) ➗ 6.28
11.9=r
Therefore radius=11.9 inches
