(x+4) * (x+3)

Step-by-step explanation:

To factor the general expression:

X²+ax+c

We need to find the numbers b and d of the factoring expression:

(x+b) * (x+d)

Where:

b*d = c

b+d = a

For the expression:

X²+7x+12

We need to find b and d that:

b+d = 7

b*d = 12

If b = 4 and d = 3, the expression could be:

(x+4) * (x+3) = X² + 4x + 3x + 12 = X² + 7x +12

area of base = $\pi r^2$

where 'r' is the radius

Step-by-step explanation:

Volume of the cylinder formula = $\pi r^2h$

volume of cylinder = area of base * height

The base of a cylinder is a circle. so we use the area of circle for the base of cylinder while finding volume

We know area of the circle is $\pi r^2$

So area of the base of cylinder is $\pi r^2$

To find volume of the cylinder , we multiply the base of the cylinder with height

To determine the base of the cylinder we need radius of the cylinder

area of base = $\pi r^2$

where 'r' is the radius
