Quiz 3 Volume Of Solids Important questions for class 10 maths chapter 13 surface areas volume; mensuration solved problems question 1: find the area and perimeter of a square whose side is 5 cm. solution: given: side = a = 5 cm. area of a square = a 2 square units. substitute the value of “a” in the formula, we get. area of a square = 5 2 a = 5 × 5 = 25. Problem 4: finding the surface area of a sphere. question: find the surface area of a sphere with a radius of 7 inches. solution: need to apply formula to calculate the surface area of a sphere is: sa = 4 * π * radius^2. substituting the given value into the formula, we have: sa = 4 * π * 7^2 = 4 * 49π = 196π square inches. Using this mensuration formula list, it will be easy to solve the mensuration problems. students can also download the mensuration formulas list pdf from the link given above. in general, the most common formulas in mensuration involve surface area and volumes of 2d and 3d figures. mensuration formulas for 2d shapes. Example 3: find the area of a circle whose radius is 6 cm. solution: yes, a circle comes under the category of 2d shapes. the area of a circle = π × r 2; where 'r' is the radius of the circle and π is a constant whose value is 22 7 or 3.14. area of the circle = π × r 2. = 3.14 × 6 2.
