WebSep 15, 2024 · Surface Areas and Volumes Class 9 Extra Questions Short Answer Type 1 Question 1. A spherical ball is divided into two equal halves. If the curved surface area of each half is 56.57 cm, find the volume of the spherical ball. [use π = 3.14] Solution: Since curved surface of half of the spherical ball = 56.57 cm 2 2πr 2 = 56.57 = 113.04 cm 3 WebApr 22, 2024 · D. Russell. You will find that a cylinder is much easier to work with than a cone. This shape has a circular base and straight, parallel sides. This means that in order to find its surface area or volume, you only need the radius (r) and height (h).However, you must also factor in that there is both a top and a bottom, which is why the radius must be …
