Can someone please solve this??

V=pi*r^2*h/3
=> h=3V/(pi*r^2)
V=6pi^2 cm^3
r=3 cm

h=3V/(pi*r^2)=6*pi^2 / (pi*3^2) = 2pi  cm

Height = 2 pi cm

The quotient of 4 and 1/5 will be greater than 4.
bixtya [17]
First, we will need to compute the quotient of 4 and 1/5
When we divide a number by a fraction, we convert the division to multiplication and then flip this fraction.
Therefore, in the given:
4 / (1/5) we will convert the division into multiplication and flip the 1/5 to 5
This will result is the following:
4 / (1/5) = 4*5 = 20

Comparing this quotient to 4, we will find that the quotient is greater than 4

Therefore, the given statement is: True
