let the height of cylinder = h radius of cylinder = r volume of cylinder =πr2h when radius = 2r & height = h/2 New volume of cylinder = π4r2(h/2) Required ratio = π4r2(h/2) : πr2h = 2:1
(3500 ÷ √1225) × √(20.25) = ? ÷ 4
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
136% of 560 - 2/7 of 630 + 45% of 420 =?
Determine the simplified value of the given mathematical expression.
1500 × 60% of 25% = ? 2
53 – 8 = ? + 126
Find the Value of
? = 6.25% of 240 + 25 2 + 17 2 – 16 × 17
