Area = pi*r2*190/360
So r2 = Area*360/(190*pi) = 399.8
and so r = 19.99 units
If you use the approximation pi = 3.14, the answer is 20.0 units.

What is the radius of a circle if it has a sector area of 662.89 and a 190 degree measure?
For A+ it's 20
The area of a sector formed by a 110 degree central angle is 50 units what is its radius?
45.33
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.
Find the area of a sector of a circle with a 2 feet radius formed by a 30 degree angle?
the formula for the area of a sector is measure of arc/360 times (pi)(radius squared) it should come out to be about 1.046 or 1.047, or 1/3(pi) the formula for the area of a sector is measure of arc/360 times (pi)(radius squared) it should come out to be about 1.046 or 1.047, or 1/3(pi)
How do you get area of sector without given radius?
if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area

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 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.
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
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.
