The areas of two similar triangles are 144 cm2 and 196 cm2 respectively. If the longest side of the smaller triangle is 24 cm, then find the longest side of the larger triangle.
The area of the curved surface of a cone is 195π . If the slant height of the cone is 12 cm, find the radius of the base
A clay cylinder of height 42 cm is converted into a cone of the same radius as that of the cylinder. If the volume of the cylinder is 52,800 cm3 , then the radius (in cm) of the cone is:(Use π =22/7)
