A nautilus shell is made up of many chambers, each chamber roughly 5% larger than the previous one. Assuming a nautilus creates a new chamber every year, and this year's chamber has a volume of 1,000 microliters, how large will the chamber created in 5 years be? If necessary, round your answer to the nearest tenth.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
