What is the radius of a circle if it had a 90 degree sector and an area if 64pi?
From your question, we can't tell whether [ 64 pi ] is the area of the circleor the sector.The area of a circle is [ pi R2 ].If [ 64 pi ] is the area of the circle, then the radius is [ 8 ], and we don't careabout the sector.If [ 64 pi ] is the area of the sector, then the area of the full circle is [ 256 pi ](because the 90-degree sector is 1/4 of the circle), and the radius is [ 16 ].
What is the approximate area of the shaded area of the shaded sector 180 degrees?
To find the area of a shaded sector with a 180-degree angle, you can use the formula for the area of a sector: ( \text{Area} = \frac{\theta}{360} \times \pi r^2 ), where ( \theta ) is the angle in degrees and ( r ) is the radius. For a 180-degree sector, the formula simplifies to ( \text{Area} = \frac{1}{2} \pi r^2 ). Thus, the area of the shaded sector is half the area of the full circle with radius ( r ).
What is the area of a 30 degree sector of a circle with a radius of 36?
Area of the circle = pi*362 = 1296*pi Area of the sector = 30/360 of 1296*pi = 108*pi square units
How do you work out the area of a sector using the angle and radius?
the area of a sector = (angle)/360 x PI x radius x radius pi r squared
How do you find the area of a sector with only radius given?
To find the area of a sector when only the radius is given, you'll need to know the angle of the sector in either degrees or radians. The formula for the area of a sector is ( A = \frac{1}{2} r^2 \theta ), where ( r ) is the radius and ( \theta ) is the angle in radians. If the angle is not provided, the area cannot be determined solely with the radius.

What is the area of a 30 degree sector of a circle with a radius of 36?
Area of the circle = pi*362 = 1296*pi Area of the sector = 30/360 of 1296*pi = 108*pi square units
What is the area of a sector whose central angle is ninety degrees and has a radius of ten inches?
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
What is the area of a sector with a radius of 8 and a 90 degree angle?
The area of a circle is given by the forumula pi x the radius squared. A 90 degree sector will occupy one fourth of the area of the circle, so the answer is: (pi x r2)/4 = (3.14 x 82)/4 = 50.24, or approximately 50 if you are calculating with significant figures in mind.
