How do you find the area of a shaded circle and the area of an unshaded circle on that is inside the other circle?
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Is the circumference and area of a circle the same?
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
Equation for area of a circle?
area of a circle = pi*r2
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
What is the area of a circle with a radius of 1?
Since area of a circle = πr^2, a circle with r=1 would have an area of π.
What is the area of the shaded sector if the circle has a radius of 4 and the central angle is 90 degrees?
An entire circle is 360 degrees. 90 deg is 1/4 of that. Area of a circle is A = pi r^2 area of this sector is (1/4) pi r^2 = (1/4) x 3.14 x 4x4 =12.56
What does it mean when you use terms of pi?
its when you leave the answer with ╥ in it e.g. if they go find the area of a circle (Pi.r.r or squared) you find the radius say 4cm then you put in in the formula so piX4X4 so you then find out 4X4 which is 16 so the area of a circle with a radius of 4cm in terms of ╥ is 16╥
How do you find the area of a circle if the circle is 8cm?
