A circle with a radius of 2.5 meters has an area of 19.63 square meters.
Use the formula: A = pi x r2. That is, area = pi x radius squared.
Volume = 1/3*pi*52*6 = 50*pi cubic m
5m-5n+5m+5n When simplified: 10m

Radius of circle: 5/2*pi m
A circle with a radius of 2.5 meters has an area of 19.63 square meters.
radius = diameter/2 so in this case it would be 2.5 metres.
Circumference of the circle: 2*pi*5 = 10*pi m
Use the formula: A = pi x r2. That is, area = pi x radius squared.
5m, taking an online math test? Pathetic.
78.5m2a = (3.14) (5m)2a = (3.14) (25m2)a = 78.5m2
A radius of 5m means a circumference of 31.4 meters.

Area = pi*r2 = pi*52 = 78.54 sq metres
circumference = 2pi5 = 31.416 m rounded to 3 decimal places
The answer depends on whether 5m refers to the radius or diameter.
