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.
What shapes all have 90 degree angles?
triangles squares rectangles i think most shapes could have a 90 degree angle except a circle
Is the radius of a circle half of a diameter?
no.the radius of a circle is the distance from the middle of the circle to the edges. no.the radius of a circle is the distance from the middle of the circle to the edges.
The circumference of a circle is 60 cm what is the radius of the circle?
The radius of the circle is: 9.549 cm
What is the radius of a circle?
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
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 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 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.
In a circle a 90 degrees sector has area 16pi ft2. what is the radius of the circle?
The radius is 8 feet.
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.

Find the area of a sector in a circle if the radius is 4 cm and the arc has degree 120?
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
If a circle has a radius of 12 cm and a sector defined by a 120 degree arc what is the area of the sector?
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
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 =======================
