The volume of a sphere is calculated like so:
v = 4*pi*r^3/3
so half sphere will have half that volume:
v = (<span>4*pi*r^3/3)(1/2)
</span>v = <span>4*pi*r^3/6
</span>plug in the data:
v = <span>4*pi*(10)^3/6
</span>v = 2094.4
that is the volume of the half sphere
We're given the hypotenuse and one side and we're looking for the missing side so use pythagorean.
20² - 16² = 144²
Square root of 144 = 12 feet
Answer:
3n^2 - 5n - 28
Step-by-step explanation:
(n - 4)(3n + 7)
3n^2 + 7n - 12n - 28
3n^2 - 5n - 28
hope this hepls!!!
