Answer:
33, 36, 39, 40
Step-by-step explanation:
Answer:
75.39 in^2
Step-by-step explanation:
circumference=2πr
30.8=2(3.14)r
30.8=6.28r
4.9=r
Now that we know the radius, we can plug it in for the area equation
area=πr^2
area=(3.14)(4.9)^2
area=(3.14)(24.01)
area=75.39 in^2
The area would be 70cm because 10 x 7 = 70
π * Diameter = 39.8in
Diameter = 12.67in
Since 18in is greater than 12.67in, the ring is not large enough for his act.
