What is the area of a circle with radius of 2m?
The area of a circle with a radius of 2m is: 12.566 m2
If the radius of a circle is doubled what happens to the area?
It quadruples. The area of a circle is Pi (about 3.14159) times the radius squared. So if you double the radius (say from 2m to 4m), you area will change from 4*Pi to 16*Pi (4 times what it was originally).
What is the area of 9m and 2m rectangle?
It would be 18 square meters. You find that out by multiplying 9m x 2m. You're welcome :)
What is the area of 4m 6m 2m 2m of a rectangle?
74
Can the area of a circle ever equal the circumference of a circle?
No, no it can't. Circumference = 2r*pi Area = pi*r2 For the area to equal the circumference pi*r2 = pi*2r so divide both sides by pi r2 = 2r so divide both sides by r r = 2 Note that circumference is in units and area is in units squared i.e. radius = 2m, area = 12.56637m2 Ciercumference = 12.56637 m
