The radius of a circle is 8ft. I have 60ft of tile. Is this enough to cover circle.
Do you mean you have 60 SQUARE feet of tile? The circle's area is much more than that.
How would you find he angle to a circle if half of it is 12 in. ??? and how owuld you find the area of a circle if the half of it is 10 in.?
if b is 1.5 what is the area of the circle in terms of pi?
To find the angle of a circle if half of it is given, you can use the following formula:
Angle of a sector = (Given length of half of the circle / Circumference of the circle) * 360 degrees
In this case, if half of the circle is 12 inches, you would start by calculating the circumference of the circle:
Circumference = 2 * π * radius
Given that the radius is not provided, let's assume it to be 'r'. Therefore, the circumference of the circle would be:
Circumference = 2 * π * r
Now, we can calculate the angle of the sector using the given length:
Angle of sector = (12 inches / Circumference) * 360 degrees
To find the area of a circle if half of it is given, you can use the formula for calculating the area of a circle:
Area of a circle = π * radius^2
Since we are given half of the circle's diameter, let's assume it to be 'd'. The radius of the circle would then be half of the diameter:
Radius = d/2
Given that half of the circle is 10 inches, we can find the diameter:
Diameter = 2 * 10 inches = 20 inches
Finally, we can calculate the area of the circle:
Area of a circle = π * (radius)^2 = π * (10 inches)^2
