The correct answer is d. Please give me brainlest I hope this helps let me know if it’s correct or not okay
Volume of the cone = 1/3π r^2 h
So, we are given that r = 9 and h = 12
plugging in all the known values
1/3 * (3.14) * 9 * 9 * 12
= 1017.36 cm³
or
≈1017.4 cm³
The answer to 75 squared is 5,625.
2i(4+5i)(4-5i) =82i
4+i nothing more can be done it is at simplest form
so

=

so your answer is
