Best Answer

to find the area of a whole circle, use the formula Area = Pi * (Radius)^2

where Pi is approximately equal to 3.14.

so the area of the circle with radium = 4 m, is 16*Pi = 50.24 m^2;

to find area of a quarter of this circle, divide the total area by 4

to get 4*Pi= 12.56 m^2

First, find the whole area.

A = πr²

A = π(4)²

A = 50.2655

Then take 1/4 of it. 12.5664 m² ■

4m

diameter or radius?

Area required = 130/360 x 16 pi ie 18.15 sq m

5.99meters is the height.

Circumference = 2*pi*4 = 25.133 meters rounded to three decimal places

The circle has an area of 16pi m2 or approximately 48m2.

A circle with a radius of 4m has a circumference of 25.133m.

4m

diameter or radius?

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).
