Answer:

pls give me brainliest

Step-by-step explanation:

A compound event is an event where there are more than 1 type of possibilities. for example, a non compound event like tossing a coin, has only 2 outcomes, either heads or tails, this is one possibility, but while tossing a die, there are various possibilities, like p(getting 1), p(getting even number), p(getting prime number), etc. this is known as a compound event.

a sample space is is where all outcomes of an event is enlisted, for example in tossing a die, sample space is {1,2,3,4,5,6}. and sample space for tossing a coin, {H,T}. Note : if 2 dices are tossed, the number of possibilities or 6^2, because there are 6 possibilities in one die and it will be 6^2 if there are 2.

a tree diagram helps in easily writing down the outcomes easily, here is an example.

What is the volume of the composite figure? (Round to the nearest hundredth. Use 3.14 for x.)
marshall27 [118]

The volume of the composite figure is the third option 385.17 cubic centimeters.

Step-by-step explanation:

Step 1:

The composite figure consists of a cone and a half-sphere on top.

We will have to calculate the volumes of the cone and the half-sphere separately and then add them to obtain the total volume.

Step 2:

The volume of a cone is determined by multiplying \frac{1}{3} with π, the square of the radius (r²) and height (h). Here we substitute π as 3.1415.

The radius is 4 cm and the height is 15 cm.

The volume of the cone :

V = \frac{1}{3} \pi r^{2} h = \frac{1}{3} (3.1415)(4^{2} )(15) = 251.32 cubic cm.

Step 3:

The area of a half-sphere is half of a full sphere.

The volume of a sphere is given by multiplying \frac{4}{3} with π and the cube of the radius (r³).

Here the radius is 4 cm. We take π as 3.1415.

The volume of a full sphere \frac{4}{3} \pi r^{3} = \frac{4}{3} (3.1415) (4^{3}) = 268.07 cubic cm.

The volume of the half-sphere =\frac{1}{2} (268.07) = 134.037 cubic cm.

Step 4:

The total volume = The volume of the cone + The volume of the half sphere,

The total volume 251.32+134.037 = 385.357 cub cm. This is closest to the third option 385.17 cubic centimeters.
