Answer:
Area = 49π
Step-by-step explanation:
circle Area = π x (radius)²
Assuming d = 14 is the diameter (which the problem really should state explicitly, not leave you to assume), then the radius is half of that.
So r = 7, where 'r' is the radius.
Area = π x r² = π(7)² = π(49)
Area = 49π is the exact answer, so it is the one I prefer.
Area = 153.86 is the decimal you get if you multiply 49 x 3.14
Hope this helps.
B . 5635.6% not for sure but I think that’s the answer
To answer this item, we let n be the number of hours that a person spend on the roller rink. We also let x be the cost or amount to paid each hour. The equation that would best represent the relationship between the total cost and the number of hours is,
