Volume of cylinder = 22/7 × (28)² × 21 = 51,744 Area of the platform to be filled = π (42)² - π (28)² = π × 70 × 14 [since volume will be the same] ⇒ 22/7 × 70 × 14 × h = 51,744 ⇒ h = 16.8m
1.55 + 2.05 + 1.5 × 11 – 20% of 10.5 = ?
Determine the simplified value of the given mathematical expression.
√( (664+ √(136+ √(59+ √(21+ √(7+ √81) ) ) ) ) ) = ?
(23 × 8) – (13 × 5) + 67 =? x 6
Simplify the following expression:
Find the value of the expression:
32 + 6 – 5 × [18 + 10 – 3 × (36 – 21)]
20.5 × 36 + 24 × 8 + ?2 = 1954
