What’s the exact volume of the figure?

890.12 cm^3

Step-by-step explanation:

The formula for the volume of a cylinder is

V=628.3185307 cm^3

or simply

V=628.32 cm^3

Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.

Next, the formula for the volume of a sphere is

so the volume of a hemisphere is half of that or:

V= 261.7993878 cm^3

or simply

V=261.80 cm^3

Finally, you add both of the volumes together to get

V= 890.1179185 cm^3

or simply

V=890.12 cm^3

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

well, if it's triangular garden, the triangle could represent the garden.
