For a circle Area is defined as: A = π(r)2 Where "A" is the area, "r" is your radius and π = 3.14 So for your circle: A = 3.14 x (15)2
706.5
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
The area of a circle is 153.86cm².find the radius of the circle
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
A circle with a radius of 4 cm has an area of 50.27 square cm.
The area of a circle with a radius of 7 cm is: 153.9 cm2
706.5 cm
What’s the answer
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
The radius is 1.27cm
Diameter = Radius*2 = 30 cm.
The surface area of a cylinder where height is 80cm and radius is 15cm equals 8953.54cm2
7.5cm (r = d/2)
double the radius to get the diameter = 30 multiply by pi (3.1415...) = 92.245 cm
ANUS
Area = (pi) (radius)2 = 225 pi = 706.858 square centimeters (rounded)
Using 3.14 as Pi the area of circle is: 379.94
176.715 cm2 (rounded)
