1- 51.496yd 2- 39.25ft 3- 163.28cm 4- 53.38mm 5- 50.24in 6-94.2ft 7-18.84yd 8- 207.24m

Step-by-step explanation:

So how you do circumference is you find the diameter and times it by pi.

for 1. you will do 8.2 times 2 for the diameter then times it by pi and get 51.496 yards.

for 2 you would do 12.5 times pi and get 39.25ft

for 3 you would do 26 times 2 which is 52 then multiply it by pi which is 163.28cm

for 4 you do 17 times pi which is 53.38mm

for 5 you do 16 times pi which is 50.24in

for 6 you do 30 times pi which is 94.2ft

for 7 you do 3 times 2 which is 6 then multiply by pi which is 18.84yd

for 8 you do 33 times 2 which is 66 then multiply by pi which is 207.24m.

2. 122.7 ft^2

3. 2123 cm^2

5. 201.06 in^2

6. 706.86 ft^2

7. 28.27 yd^2

8. 3421.19 m^2

Step-by-step explanation:

Use the equation area=pi r(squared) to continue finding the area
