Circumference of any circle = (pi) x (diameter) = (pi) x (2 x radius) = 14 pi = 43.982 (rounded)
Remember in taxicab geometry pi=4
Not in this case, my friend. Taxicab geometry is non-Euclidean. How far will a taxi drive in a city around a circle of radius 7? Picture four points in the cardinal directions each 7 blocks from downtown. How far to drive from one to all three others and back? Label them N, E, W, and S (not very original, but mnemonic). From N to E, no matter which way you go as long as you are heading south and east, is 14 blocks. Continuing around is going to be 56 blocks. â–
The equation for a circle is PiD. The diameter is double the radius, so it is 7 yards in this case. The circumference is 7*PI. Which is approximately 21.98.
if you mean a radius of 5 units then the answer is 78.54 APEX
perimeter or circumference = 2*pi*7 m
Circumference of a circle = 2*pi*radius or pi*diameter 7*pi = 21.99114849 units Therefore the circumference ot the circle is 22 units correct to the nearest unit.
21.99113 approximately... * * * * * Accurate to 5 decimal places but WRONG by a factor of 2. Circumference = 2*pi*radius so radius = 7 cm => circumference = 43.98 cm.
If a circle has a circumference of 43.98 the radius is: 7 (6.999).
The radius of the circle is 7.
Circumference of a circle = 2*pi*radius or diameter*pi
The circumference is about 43.98 inches. The circumference of a circle is diameter (radius x2) x pi (3.14).
Circumference=πd thefore it is 44
circumference of a circle = 2*pi*radius or diameter*pi
44
43.982"
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
The radius is 7 inches.
Assuming that "it" refers to diameter, the radius is 7 cm and the circumference is 44.0 cm.
The equation for a circle is PiD. The diameter is double the radius, so it is 7 yards in this case. The circumference is 7*PI. Which is approximately 21.98.
