In a circle a 90 degree sector has has area 36 pi ft squared what is the radius of the circle?
The radius is 12
In the diagram and ampangleABC 90 and deg. What is the radius of the circle?
I can see no diagram.
How much area is 90 feet Radius?
If you mean a circle, use the formula for the area of a circle: A = pi x r2.
What is the area of the shaded sector if the circle has a radius of 3 and the central angle is 90 degrees?
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
If a line is tangent to a circle what angle is formed if a radius is drawn to the point of tangency?
90 degrees. QED.
In a circle a 90 degrees sector has area 16pi ft2. what is the radius of the circle?
The radius is 8 feet.
In a circle a 90 degree sector has has area 36 pi ft squared what is the radius of the circle?
The radius is 12
What is the radius of a 90 degree circle?
The radius is a lenght, and it's impossible to find out the radius if you don't give any information about the size of your circle.
Quarter of a circle?
25%. 45 degrees. Radius.
What is the circumference of an 90 cm circle?
circumference of a circle = 2*pi*radius or pi*diameter
What is th radius and diameter of a circle with a circumference of 90 inches?
Circumference = 2*pi*radius or circumference/2*pi = radius 90 inches/2*pi = 14 inches in radius =======================
In the diagram and ampangleABC 90 and deg. What is the radius of the circle?
I can see no diagram.
What happens between a radius and a tangent in a circle?
A tangent is always perpendicular to the radius of a circle. A radius is a straight line going from the center of the circle to the circumference (edge) of the circle. A tangent is a straight line outside the circle that touched the circle at one (and only one) point. When a tangent touches the outside edge of the circle at the same point where a radius touches the edge of the circle, the angle between the radius and tangent line is 90 degrees meaning they are perpendicular.
How much area is 90 feet Radius?
If you mean a circle, use the formula for the area of a circle: A = pi x r2.
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 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 does perpendicular mean mathematicalywhat is radius?
Perpindicular lines are like the lines in the letter "T". The intersect each other at a 90 degree angle. A radius is the distance from the center of the circle to the circle itself. It is half the circle's diameter.
