The volume of a cylinder with radius ‘r’ and height ‘h’ is measured by:
If the sector of circle of radius 16 cm has an area of 140 cm² then the angle subtended at center of circle is:
If the radius is 21 cm and the angle at center of circle is 140° then the length of the arc is:
The most frequent occurring observation in the data is called:
Circumference of the circle is calculated by:
The formula used to measure area of circle is:
If sector of circle of radius 16 cm has an area of 140 cm² then angle subtended at center of circle is
