Find the volume of each three dimensional figure (3 problems please help)

Mathematics
1 answer:
grin007 [14]3 years ago
8 0

Answer:

Step-by-step explanation:

1) The solid is a cube. The formula for determining the volume of a cube is expressed as

Volume = s³

s = 5 cm

Therefore,

Volume = 5³ = 125 cm³

2) The solid is a cuboid. The formula for determining the volume of a cuboid is expressed as

Volume = lwh

l = 10 inches

w = 5 inches

h = 2 inches

Therefore,

Volume = 10 × 5 × 2 = 100 inches³

3) The solid is a square base pyramid. The formula for determining the volume of a square base pyramid is expressed as

Volume = Area of square base × height

Area of square base = 3² = 9 m²

h = 10 m

Volume = 9 × 10 = 90m³

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.

If line BA is a midsegment of triangle XYZ, find x.
DIA [1.3K]
For midsegment theorem
And parallels lune are twice

So AB = YZ /2

AB = 10/2 =5

BUT AB = X–1 =5

X–1 = 5 = X = 1+5 =6

X =;6

M+3=5:m=? please give me explained​
storchak [24]

Answer: M = 2

Step-by-step explanation:

Given equation: m+3=5

You need to isolate m so you can find its value. Subtract 3 from the left side, and do the same to the right side. Subtracting 3 from 5 as well makes the number become 2 on the right side of the equation. Therefore, m=2.

A rule you should always remember is when you have a value on each side of the equal sign, whatever form of addition, subtraction, multiplication, or division should be done to the other side as well.

Which comparison is not correct?
strojnjashka [21]

Answer:

the 2 one is wrong

Step-by-step explanation:

the 2 would be greater than the 9 sense both the numbers are negative and the bigger the negative number is the less amount it is so -9 is smaller than -2
