2 km Find the volume of the sphere. Show your work.

densk [106]

Answer:

See answer below

Step-by-step explanation:

$V = \frac{4}{3} \pi r^3$ 2km = radius

$V=\frac{4}{3}\pi (2)^3$

$V = \frac{4}{3}\pi (8)$

$V = \frac{4}{3}(8)\pi$

$V =\frac{32}{3}\pi$ $\pi =3.14$

$V = \frac{32}{3}(3.14)$

$V = 33.493$

V≈ 33.49

Using π on the calculator

$V = \frac{32}{3} \pi$

$V = 33.510$

V ≈ 33.51

AC=4, AE=7, AD=10, what is the length of AB? A: 1 3/7 B: 2 1/2 C: 5 5/7 D: 17 1/2

Answer:

C. $AB = 5\frac{5}{7}$

Step-by-step explanation:

When two polygons are considered similar, the ratio of their corresponding sides would also be equal.

Since ∆ABC and ∆ADE are similar, $\frac{AE}{AC} = \frac{AD}{AB}$

$\frac{7}{4} = \frac{10}{AB}$

Cross multiply

$7*AB = 10*4$

$7*AB = 40$

Divide both sides by 7 to find AB

$\frac{7*AB}{7} = \frac{40}{7}$

$AB = \frac{40}{7}$

$AB = 5\frac{5}{7}$
