Two chords AB and CD of a circle intersect at E such that AE = 3.4 cm, BE = 4.2 cm and CE = 2.6 cm. What is the approximate length of DE?
In the figure given below, a circle is inscribed in a triangle ABC. If AB = 18 cm, BC = 14 cm and AC = 16 cm, then find the length of YC.
In a circle, the length of a chord AB is 48 cm & radius is 25 cm. Find the distance between centre and chord.
- Find the angle subtended at the center by an arc of a sector whose area is 462 cm² and radius is 21 cm. (Use π = 22/7)
- What is the area of a circle whose radius is equal to the length of a cube’s edge, if the cube's total surface area is 1,944 cm²? (Take π = 3)
In a circle of radius 13 cm, a chord is 5 cm from the center. Find chord length.
A sector of a circle has a central angle of 60°. If the radius of the circle is 14 cm, what is the area of the sector?
- The area of a circle is nine times its circumference (numerically). What is the diameter of the circle?
- The numerical value of the area of a circular park is ten times the numerical value of its perimeter. Find the diameter of the park.
In a circle, two chords AB & CD are produced at P which is outside the circle . If PA= 18 cm, AB= 12 cm , PC = 6 cm then find CD.
