Answer: c
Step-by-step explanation: edge 2021
Area = πr². So you have the diameter which is 56 millimeters. And the radius (r) is half the diameter, so the radius would be 28 mm. Square 28 would be 784, multiplied by π would equal 2463.00864mm. Rounded to the nearest hundredth would be 2843.01mm².
The answer is 21 m squared
3(5)=15
3(2)=6
15+6=21
I think the answer is (-8,-26)
