Circumference not required, and in any case doesn't make sense for a radius of 11; it should be 69. A = pi x r x r = 121 pi = 380.12
11 = sqrt of 121. it is a circle centred on the origin think what would happen on the line x=0 (The y axis) the equation simplifies to y2 = 121 or y =11 you can also think of eqn of a circle as x2+y2=r2
11 units. (It is the square root of 121, and A=S^2 => 121=S^2 => S=11.)
11 meters
121 cubed = 121 x 121 x 121 = 1,771,561
Radius = 6.21
6.21
Radius = 6.206 units, approx.
radius = 121/(2Ï€)
Using 3.14 as Pi the area of circle is: 0
The radius a circle with area of π*121 yd2 is 11 yds [= sqrt(121)] The circumference, therefore, is 2*11*π = 22*π yards.
Area of the circle: pi*11^2 = 121*pi square units
380. 1 cm2 is the area of the circle.See: the area of a circle is pi (3.14) times radius2 .3.14 x 121 = 380.1
Area of the circle: pi*11^2 = 121*pi square units
Radius = 1111
the area can not be cubed. the area is always squared. volume is cubed. the formula for area is pie multiplied by radius squared. your formula for your circle is... A = 121pi in2 the radius in your circle is 11 inches the formula for circumference is two times pi times the radius C = 2 * (3.14159) * 11 your answer is 69.11498in
The formula is PI * (R ^ 2) Radius is half the diameter. so PI * (11 ^ 2) PI * (121) 3.14 * 121 = 379.94
