Question
Calculate the difference between the area of a wall
having dimension 22 cm X 23 cm and the area of a spherical bowl having diameter 14cm.Solution
Area of the wall = 22 X 23 = 506 cm2Area of the spherical bowl = 4 X π X r2Here, radius of the spherical bowl = Diameter/2Radius of the spherical bowl = (14/2) = 7 cmArea of the spherical bowl = 4 X (22/7) X 7 X 7 = 616 cm2Required difference = 616 - 506 = 110 cm2
13.99% of 299.99 ÷ 7.17 = ? ÷ 16.15
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
2 (1/4)% of 7999.58 + {49.06% of 898.87} + √143.14 – 19.99% of 1499.63 - (52 - 41) = ?
√1024.21 × √624.89 ÷ 4.98 + 11.99 × 4.01 = ?
?% of 1200.22 + 319.82 = 3.99 × 295.64
? 2 + (39.99 × 10.99 + 7.01) - (39.99 × 2.99 2 + 21.99) = 21.99 × 23.01
510.11 ÷ 16.98 × 5.14 – 119.9 = √?Â
Solve the given equation for ?. Find the approximate value.
(35.86 × 15.14) ÷ 9 + √(288.89) × 4.03 = ?
...24.75% of 20.125% of 30.05% of 2196.06 = ?Â
? + 163.99 – 103.01 = 24.01 × 6.98
