Answer: About 14.14 in^3

Step-by-step explanation:

We know that the circumference of a sphere is C=2πr. We are given that the circumference is 9.42 in. We can find the radius to get our volume.

$9.42=2\pi r$

$4.71=\pi r$

$r=1.5\\$

Now that we know radius, we can find our volume.

$V=\frac{4}{3} \pi r^3$

$V=\frac{4}{3} \pi (1.5)^3$

$V=14.14in^3$

Sierra is saving money to buy a bike the bike costs $245. she has $125 saved and each week she adds $15 to her savings. how many

beks73 [17]

You should start with an equation.
$245 = 125 + 15x$
The 'x' represents the week.

so now, we have to subtract 125 from the total amount which is 245.
$245 - 125 = 120$
now we have
$120 = 15x$
to find 'x', we must divide 15 on each side
$\frac{120}{15} = \frac{15x}{15}$
we are now left with
$8 = x$
that means Sierra will have 8 weeks until she has enough money to buy the bike
