Plastic sphere volume=4/3 times pi times rasius^3
4/3 times 3.14 times 18^3=24416.6

rubber ball whole=4/3 times 3.14 times 22^3=44579.6

subtract
44579.6-24416.6=20163


the answer is 20163 in^3

The sum of the series below is 10,900. how many numbers, n, are in the series? 19 20.5 22 23.5 ... 181
JulsSmile [24]

There are 109 terms in given series.

According to the statement

we have given that the sum of series is AP series and

This is 19 20.5 22 23.5 ... 181

And the sum of series is 10,900

Now, we have to find the number of terms in the series.

Then we use the summation formula which is

S = n/2 (a + L)

Substitute the all given values in it like

L = 181

A = 19 and S= 10,900

then

10,900= n/2(19+181)

10,900= n/2(200)

After solve the equation for n

10,900= 100n

n = 10,900 / 100

n = 109

There are 109 terms in given series.

So, There are 109 terms in given series.
