Area = pi*62 = 113.097 square cm to 3 dp
64 pi ie just over 201 sq cm
3850m is the area of the a circle whose radius of 7meaters
The area of a circle is calculated with the formula πr2, where r is the radius. Therefore, the area of a circle with radius 6cm would be π(6)2 = (36)π, or approximately 113.097 square centimeters.
A circle with a radius of 11m has an area of ~380.13 m2
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
The answer depends on what the "6cm" refers to.
C = ~37.7 cm A = ~113.1 cm2
It depends on the relationship between the rectangle and the circles.
12 cm.
6/2 = a radius of 3 cm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
The formula for the circumference of a circle is C = 2πr, where C is circumference, π is pi (approx. 3.142), and r is the radius. So, for a circle with a radius of 6cm, C = 2(3.142)(6cm) = 18.852cm Rounding to the proper number of significant figures, this answer would be 20cm.
12 cm
The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
Since the diameter is always twice the length of the radius, the length of the radius is 6cm.
The circumference of a circle = 2*pi*radius or diameter*pi
A ≈ 28.27cm2
