erastovalidia [21]

Answer:

Solution,

Diameter (d)=16 ft

Radius(r)=8 ft

Volume of sphere

 $= \frac{4}{3} \pi \: {r}^{3} \\ = \frac{4}{3} \times 3.14 \times {8}^{3} \\ = \frac{4}{3} \times 3.14 \times 512 \\ = 2144.7 \: {ft}^{3}$ 

hope this helps..

Good luck on your assignment..

A maple tree is 16 yards tall and its shadow is 12 yards long. A nearby observation tower is 12 yards tall. How long is the obse

pashok25 [27]

Answer: 9 yards

Step-by-step explanation:

Given

The maple tree is 16 yards tall and its shadow is 12 yards tall

Suppose the angle made by the maple tree is x

$\Rightarrow \cos x=\dfrac{12}{16}$

For the tower also, the angle made by the tower and its shadow is x

Suppose the length of the shadow is y

$\Rightarrow \cos x=\dfrac{y}{12}$

Substitute the value of $\cos x$

$\Rightarrow \dfrac{y}{12}=\dfrac{12}{16}\\\\\Rightarrow y=9\ \text{yards}$

For any circle, which ratio is equal to the number π? Select all that apply.

Elza [17]

Answer:

circumference - diameter

circumference - 2 times radius

area - radius squared

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$ or $C=2\pi r$

where

D is the diameter and r is the radius

therefore

$\pi =\frac{C}{D}$ or $\pi =\frac{C}{2r}$

The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius

The area of the circle is equal to

$A=\pi r^{2}$

therefore

$\pi =\frac{A}{r^{2} }$

The number pi is the ratio Area - radius squared

A painter leans a 20 foot ladder against a house so that it touches the house 11 feet from the ground. How far from the base of

gogolik [260]

This problem involves using the Pythagorean Theorem which is a^2+b^2=c^2

We already have the values of a and c, but b is unknown. So we plug in: 11^2+b^2=20^2

121+b^2=400

b^2=279

b=sqrt(279)

b=16.7

So the answer is about 16.7 ft

Hope this helped!
