The volume of a sphere is given by the formula V =⁴⁄ ₃πr3The volume of a sphere with radius 7cm = ⁴⁄ ₃π73 = 1436.76 cm3 (to 2 dps)
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
153.94 square cm
Area of the circle: pi*7squared = 153.93804 square cm
To calculate the surface area of a cylinder, you need to add the areas of the two bases (top and bottom) and the lateral surface area. The formula for the lateral surface area of a cylinder is 2πrh, where r is the radius and h is the height. Given the radius is 7cm (half of the diameter) and the height is 18cm, the lateral surface area is 2 * π * 7 * 18 = 252π cm². The total surface area is the sum of the lateral surface area and the areas of the two bases, which is 252π + 2(πr²) = 252π + 2(π*7²) = 252π + 98π = 350π cm², or approximately 1099.65 cm².
