Answer:
2.58, 2.6, 2 5/8, 2 2/3
Step-by-step explanation:
2.58, 2.6, 2 5/8 can be converted into 2.625, and 2 2/3 can be converted into 2.66 with 6 being repeated over & over.
To calculate the area it is pi*r^2
so since r = 1/2 d
2.5^2 * pi = area
or
19.625
7+7+7=21 is the same as saying 7 times 3+
=21
