HELP!!Part B What is the approximate volume of each slice that Hattie's grandma cut? (arc length of each slice is 3 in, vol. of
GalinKa [24]

The approximate volume of each slice will be 63.5 inch². The total cake is divided into the four cylindrical slice.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

The volume of the slice is;

\rm V = \pi r^2 h\\\\\ \rm 81 \pi = \pi  \times (r)^2 \times 4 \\\\ r= 4.5 \ inch

If the grandma cut four pieces, is the approximate volume of each slice that Hattie's grandma cut will be;

The approximate volume of each slice will be;

\rm V = \PI r^2 h \\\\ \rm V = 3.14 \times (4.5)^2 \times 1 \\\\ V=63.5 \ inch^2

Hence, the approximate volume of each slice will be 63.5 inch².

What is the division algorithm for 7 and 192?
Mandarinka [93]

Answer:

We have a formula for division algorithm  a= bq+r            (1)

a is the greatest integer between the two given integers

And b is the other integer

q is the quotient

r is the remainder

here we have a=192 and b=7  substituting values in equation (1) we get

192 = 27 *7 + 3                       (2)

now  substitute quotient from equation (2)  in place  of a  that is a=27  and remainder  in place of b that is b =3 in equation as below

27= 9*3 +0

we will proceed till we get remainder zero.
