3. In order to determine the formula for the volume of a sphere, 2 composite shapes are drawn within the sphere. Which of the following
formulas accurately shows the calculation for a single hemisphere of a sphere that was made by the composite formula of VCylinder - VCone

Option B:

Volume of composite figure is .

Solution:

Composite figure is made of cylinder and cone.

Radius of cylinder and cone are equal.

Radius of cone and cylinder = r

Height of cylinder and cone are equal to the radius.

Height of cylinder and cone (h) = r

Volume of cylinder =

Volume of cone =

Volume of composite figure = Volume of cylinder - Volume of cone

Take LCM for 1 and 3 and make the denominator same.

Volume of composite figure is .

Option B is the correct answer.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

im new, sorry if this is wrong.
