Answer:
452.4 ft
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr . . . where r is the radius
Filling in the given number, we find the circumference to be ...
C = 2π(72 ft) = 144π ft ≈ 452.4 ft
The distance around the outside edge is about 452.4 feet.
Answer:
20/9
Step-by-step explanation:
Turn 2_2/3 into fraction.
(2 x 3) = 6 + 2 = 8: fraction- 8/3
5/6 x 8/3 = 20/9
16 x 3/8 so 16/1 x 3/8 = 48/8. 48 divided by 8 is 6. So 6 inches.
Each increases by a certain amount called the common difference
4.4-2.8=1.6
6-4.4=1.6
7.7-6=1.7
hmm, some error
maybe you meant 7.6
common difference is 1.6
answer is C
