Volume of cone = Area of base X height ÷ 3 So, height of the cone = 1232 ÷ 154 X 3 = 24 cm Area of the base = πr2 (Where 'r' is the radius) 154 = (22/7) X r X r Or, r2 = 49 So, r = 7 (As radius cannot be negative) Slant height of cone = √(radius2 + height2) So, slant height = √(72 + 242) = √(49 + 576) = 25 cm
35% of 240 – 6 2 = ? 2 – √256
2 X 25 + (30% of 80) ÷ (10% of 120) = ?
5760 ÷ 45 × 15 = ?
(33 + 6.25% of 4096) = ? + 2 × 119
24% of 150% of 500 + 140 = ? × 8
(8 x 9) ÷ 5 + ?2 = 23.4
The valueof2 of5– 1/2 −[4÷2– 1/3 −{3/4−(5– 1/2 – 3/4 )}]is :
(49 x ?) / 3.5 + 389 = 627
32% of 4080 + 24% of 540 = ? % of 3200
