Question

4 Find the height of the cylinder whose volume is 7040 cm and radius is 8 cm. Take 1​

Answer 1

Answer:

$7040 = \pi \times 8 \times 8 \times h \\ \\ 7040 \times 7 \div 22 = 8 \times 8 \times h \\ \\ 2240 = 8 \times 8 \times h \\ \\ 2240 \div 64 = h \\ \\ 35 = h$

Answer 2

Answer:

35

Step-by-step explanation:

volume of a cylinder=πr^2h

7040=22/7*64*h

7040=22*64/7*h

7040=1408/7*h

move h into LHS side

7040/h=1408/7

by cross multiplication method

7040*7=1408*h

move h into LHS side

h=7040*7/1408

h=35
