Answer:

∠ 1 = 124°, ∠ 2 = 98°, ∠ 3 = 82°, ∠ 4 = 124°, ∠ 5 = 98°

Step-by-step explanation:

See the given diagram.

Since ∠ 1 + 56° = 180°, ⇒ ∠ 1 = 124°

Now, 56° + 26° + ∠ 2 = 180°, ⇒ ∠ 2 = 98°

Now, ∠ 2 + ∠ 3 = 180°, ⇒ ∠ 3 = 180° - 98° = 82°

Again, ∠ 5 + 82° = 180°, ⇒ ∠ 5 = 98°

And, ∠ 4 = 26° + ∠ 5 = 26° + 98° = 124° (Answer)

Find the volume of the composite figure to the nearest tenth. Use 3.14 for pi.

Vilka [71]

Given:

In the given fig,

The radius of the cylinder = 15 ft

The height of the cylinder = 26 ft

The height of the cone = 21 ft

The radius of the cone = 15 ft

To find the volume of the cone, the volume of the cylinder and the composite figure.

Formula

The volume of the given composite fig is

$V = V_{1} +V_{2}$

where, $V_{1}$ be the volume of the cone.

$V_{2}$ be the volume of the cylinder.

$V_{1} = \frac{1}{3} \pi r^{2} h$ , r be the radius and h be the height.

$V_{2} = \pi r^{2} h$ , r be the radius and h be the height.

Now,

Putting, r = 15, h = 21 and π = 3.14 we get,

$V_{1} = \frac{1}{3} (3.14)(15^{2} )(21)$ cube ft

$V_{1} = 4945.5$ cube ft

Again,

Putting,

$V_{2} = (3.14)(15^{2} )(26)$ cube ft

$V_{2} = 18369$ cube ft

Therefore, the volume of the composite fig = (4945.5+18369) cube ft = 23314.5 cube ft

Hence,

a) The volume of the cone is 4945.5 cube ft.

b) The volume of the cylinder is 18369 cube ft.

c) The volume of the composite figure is 23314.5 cube ft.

Two business partners, Ellen and Bob, invested money in their business at a ratio of

algol13

Hi there, Rukie! This problem can be solved by divided the number given by one of the ratios, and multiplying that answer by the other ratio. Since Bob invested the greater amount, we can divide his investment ($450) by 8, getting the answer of 56.25 (that's the unit of the ratio). We can then multiply that number by 7 to calculate Ellen's investment, which comes out to be $393 dollar and 75 cents. Hope that helps!
