What is the volume of a hemisphere with a radius of 26.7 m, rounded to the nearest tenth of a cubic meter?

Step-by-step explanation:

a hemisphere is half a sphere.

And if the formula for the volume of a sphere is:

we must calculate the volume of the sphere and in the end divide by two to find the volume of the hemisphere.

Since the radius is:

substituting this into the formula for volume:

this is the volume of the total sphere, thus the volume of a hemisphere is:

rounding to the nearest tenth:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
