Mrs. Duncan is building a circular table. The piece of wood for the top of the table has a radius of 2 feet and has a height of a 1/2 foot. If the density of wood is 50 lbs
per cubic foot, how heavy is the piece of wood in lbs. Show all work and round your
answer to the nearest tenth of a Ib.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

, 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
