Agroup of 6 children and 7 adults are going to a movie. child tickets cost $4, and adult tickets cost $8. how much will the movie tickets cost in all?

$84

Step-by-step explanation:

Add the two totals together: 56 and 28.

56 + 28 = 84

So, the movie tickets will cost $84 in all.

we have

----> the length side of the cube is equal to the diameter of the cylinder

so

step 2

Find the volume of the cylinder

The volume of the cylinder is equal to

we have

substitute

step 3

The volume of the figure is equal to
