Answer:
when adding you just line the decimals up like this, let's say you had to add 1 to 2.58.
2.58
+ <u> 1 .00</u>
3.58
when multiplying you might have to move it, say you had to multiply 1.5 by 2.2. (you don't have to line up the decimals like with addition)
1 .5
<u> </u><u>×</u><u> 2.2</u>
30
<u> </u><u>+</u><u> 300</u>
3.30
1.5 has one decimal place and 2.2 also has one decimal place so you put those 2 decimal places in your answer.
sorry if this is a bit confusing lol

40+20=x
60=x

Step-by-step explanation:
Answer:
V = 180 ft^3
Step-by-step explanation:
The volume of a cone is found by
V = 1/3 pi r^2 h where r is the radius and h is the height
The diameter is 12 so the radius is 1/2 the diameter or 1/2(12) = 6
The height is 5 and we are using 3 for pi
V = 1/3 (3) *6^2 *5
V = 180 ft^3
