answer:
c.962.51 in^3
step-by-step explanation:
so first we have to find the radius
in order to find the radius we divide 12 1/4÷2
which equals 6.125, now we have our radius
now we need to set up the formula
v=4/3πr^3
v=4/3π6.125^3
v=962.51
to check your work you can goo-gle volume of a sphere **you should get the same answer**
good luck :)
hopefully, this helps
have a nice day !!
