Describe an addition problem that you may need to regroup hundredths to solve

Lets consider a basic problem of addition of three decimal numbers which includes hundredths .

When we add all the three decimal numbers , we regroup all the digits according to their place value (start from left) and then add them.

Now,

Addition of digits on their hundredths place=

Addition of digits on their tenths place =

Addition of digits on unit place =

Arrange the answer according to their corresponding place, we get 18.19

Hence,  

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
