The answer is Pi R2 The answer is Pi R2
The volume of this sphere is: 1,092,900,000,000 cubic km
If C = 449,000 km then radius = 71,500 km
It is: 270/360*pi*2 squared = 3*pi square km
Circunference is equal to 2pi * radius, there for 14 divide by two equal 7 because radius is half of diameter then you will need to put in your calc... 2(3.1416)*7 and the answer will be the circunference. Or you can simply say 14 pi I think the magic word here is "approximate", from which I believe the question hopes you will use the well known approximation for pi (=22/7). So pi times diameter is 22/7 x 14 = 44km
That the formular for the circumference of a circle (pii D)The answer should be 4.254
A circle with a radius of 1.8 km has a circumference of 11.31 km
A circle with a radius of 126 km has a circumference of 791.68 km.
A sphere with a radius of 687 km has a volume of 1,358,184,658.3 km3
The volume of this sphere is: 1,092,900,000,000 cubic km
The radius is 71,461 km
The circumference of a circle with a radius of 1.5 km is: 9.425 km (C = r x 2 x Pi).
There is no error. The Earth is NOT a sphere, it is an oblate spheroid. This is caused by the fact that it is spinning. The spin makes the middle (the equator) bulge out. Thus if you measure the radius to the equator it is 6,378.1 km, while if you measure the radius to a pole it is 6,356.8 km.
If C = 449,000 km then radius = 71,500 km
Circumference of circle: 2*pi*13.1 = 82.30972752 km
If 11.6 km is diameter, then 11.6 * pi = 36.4425 km circumference If 11.6 km is radius, then 11.6 * 2 * pi = 72.8850 km circumference
C = 31.4 km
