Can someone show me how to figure out this problem on subtracting

Since 7-(-11) is in absolute value you have to change it to 7-11

In absolute value a positive is a positive and a negative is a positive.

When subtracting a smaller number from a bigger number you have to remember that it will always be negative. So just subtract 11 from 7 and add a negative sign.

11-7=4 so 7-11=-4.

If it wasn't in absolute value it would be different.

I hope that helps!

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
