Answer:
2660.94km³
Step-by-step explanation:
the volume V of a cylinder is given by πr²h, where r is the radius and h is the height and π = 3.1416
r = diameter/2 = 22/2 =11km
V = 3.1416 * 11² * 7 = 2660.9352 km³
V = 2660.94km

Answer:
530.66 cm²
Step-by-step explanation:
A formula for the area of the circular disc can be written as ...
A = C²/(4π)
A = (81.64²)/(4·3.14) = 6665.0896/12.56
A = 530.66 . . . . square centimeters
