Answer: 63pi cm³

Step-by-step explanation: To find the volume of a cylinder, start with the formula for the volume of a cylinder.

Volume = \pi r^{2}h

In this problem, our cylinder has a radius of 3 cm and a height of 7 cm so we can plug this information into our formula.

Volume = (\pi) (3 cm)^{2} (16 cm)

Let's start by simplifying the exponents. Remember that 3 cm² is equal to 3cm multiplied by 3 cm or 9 cm².

Volume = (\pi) (9cm^{2}) (7 cm)

Volume = 63\pi cm^{3}

Can someone please clearly and correctly work out Q19? Would appreciate it a lot! :)
DiKsa [7]
x^{2} +10x+30
I always start by moving the last term to the other side
x^{2} +10x=-30
To complete the square you take term 'b' , divide it by 2 then square it
( \frac{10}{2} )^2 = 25
We have to add 25 to what we have and what you do to one side you have to do to the other
x^{2} +10x+25=-30+25
x^{2} +10x+25=-5
Now we factor what is on the left side of the equation
(x+5)^2=-5
The last step is to move our right side of the equation back over 
(x+5)^2+5 - which is your answer :)))
