A machine takes a piece of plastic in the shape of a hemisphere and carves out a cone from it. The radius of both the hemisphere and the cone is 3 cm and the cone has a height of 3 cm. What is the volume of the remaining plastic solid in the cubic centimeters? Leave answer in terms of pi.

i think is g(1)=-1.

hope that i can

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
