What is the length of the circle radus if the quation for the circle is x2 plus y2 equals 1?
The ' 1 ' in that equation is the radius.
What is the length of a chord of the circle x2 plus y2 equals 72 which is tangent to the circle x2 plus y2 equals 18?
The circles are concentric with centre (0,0). The radius of the outer circle is sqrt(72), that of the inner circle is sqrt(18). By Pythagoras, the length of the semichord is sqrt(72 - 18) = sqrt(54) units. Therefore the chord is 2*sqrt(54) = 6*sqrt(6) = 14.679 units (approx).
The equation for a circle is x2 plus y2 equals 100 What is the length of the circle's radius?
10 Both the x-intercept (y=0) and the y-intercept (x=0) have a length of 10 units.

What is the length of the circles radius for the equation x2 plus y2121?
If you mean: x^2 + y^2 = 121 then the radius is the square root of 121 which is 11
The equation for the circle here is x2 plus y2 equals 36 What is the length of the circle's radius?
sqrt 36 ie 6
What is the length of a chord of the circle x2 plus y2 equals 72 which is tangent to the circle x2 plus y2 equals 18?

The equation for the circle below is x2 plus y2 equals 121 What is the length of the circles radius?
11 = sqrt of 121. it is a circle centred on the origin think what would happen on the line x=0 (The y axis) the equation simplifies to y2 = 121 or y =11 you can also think of eqn of a circle as x2+y2=r2
How do you find the area of each cylinder to the nearest whole number?
The Area of a rectangle is LxW . The area of a circle is PI x RxR where R is the radius of the circle. The Circumference or distance around a circle is 2xPIxR. To find the surface area of a cylinder with radius R (the radius of the circles at the top and bottom) and Length L(how tall the cylinder is) you first find the area of the circles on the bottom and top - then add it to the area of the tube part. If you unwrap the tube, it becomes a rectangle with the width 2xPIxR (since it was wrapped around the circles on top and bottom), and the Length L( how tall it is) . So it will be 2 circles plus the rectangle. 2 (PIxRxR) + 2xPIxRxL. Then round it to the nearest whole number. If the number on the right side of the decimal point is 5 or more, round up to the next whole number otherwise leave it the same. Then drop the numbers on the right side of the decimal point.
