This is a cylinder and the formula for the surface area of a cylinder is :

2πrh+2πr^2

^ means to the power of

The radius is 15

The length is 18

2(3.14)(15)(18) + 2(3.14){15}^2

Part 1:

Find the products (4m+5)(3m-6)
Vesnalui [34]

Answer:

12m^2 - 9m -30

Step-by-step explanation:

So rewrite the equation to this:

4m * 3m

4m * -6

5 * 3m

5 * -6

Now solve:

4m * 3m = 12m^2

4m * -6 = -24m

5 * 3m = 15m

5 * -6 = -30

Now add them together in order:

12m^2 - 24m + 15m - 30

Simplify -24m and 15m:

12m^2 - 9m -30

Thus

12m^2 - 9m -30 is the answer

Hope this helps!
