Area of circle = PI * radius^2, so PI * 6^2 = 113.09733553 square feet.
The answer is 904.77792 cm cubed.
The formula for calculating the area of a circle is:rÂ²Ï€So, the area of a circle with a diameter of 6 inches (with a radius of 3 inches) is:3Â²Ï€ = 9Ï€ â‰ˆ 28.2743 inÂ²
Area of sector = 60/360ths ie 1/6th of the total area; Total area = 12 x 12 x 3.14 = 452.16 cm2 Area of sector = 452.16/6 = 75.36 cm2
The area of a circle with radius r is pi*r*r where pi = 3.1416 approx. When r = 6 cm, the area is 113.1 sq cm.
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
If the diameter is 12 cm the radius is 6 cm.
r = 1.38 cm
area of circle is πr² (3.14)(6)² 3.14 * 36 = 113.45 cm² ■
It is approx 113.1 cm squared.
A circle with a radius of 6 cm has an area that is about 113.1 cm. 3/4 of that is 84.825 cm
If the diameter is what you are talking about that is 6 cm, you must divide that number by two to find the radius because the radius is half a diameter. The radius of a circle with a diameter of 6 cm. would be 3 cm.
Radius of a circle is half of its diameter and so 12/2 = 6 cm
