Answer:
1. 16π
2. 112π
3. 351.68
Explanation:
Area of a circle = πr^2
Substitute...
=4^2π
=16π
To find the how much fluid it can hold, just basically find its volume. To do that, you mutiply the area of the base by the height. So...
16π*7=122π
You then just subsitute π by 3.14 so...
122(3.14)=351.68
