Answer:
3.14 = pi
1.) R = 1.5 and A = 7.065
2.) D = 28 and A = 615.44
3.) R = 10 and A = 314
Step-by-step explanation:
R = 0.5×d
Area of circle = π×r²
The difference between the two is 14,867 feet
The answer is 40 because a quarter of 40 is 10
Tenth? It would be 4.8 (5 and up you round up, look at the digit beside the one you are rounding!)
