Find the volume of the cylinder leave your answer in terms of "pie".

Rainbow [258]

To leave something in terms of pi means that you don't have to multiply any numbers by pi when solving; you would just add it to the end. This makes the math much easier to do.

V=pi*r^2*h
V=pi*6.5^2*8
V=338pi

3 There are 5 times as many boys as girls in a school.

Dafna1 [17]

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810 Eqn 1

y = 5x Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

$\frac{6x}{6}=\frac{810}{6}\\x=135$

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675
