A circle has an area of 256 square inches. If the radius of

RSB [31]

Answer:

Option C (4096π in²)

Step-by-step explanation:

Area of the circle = 256π in²

We know that $Area=\pi r^{2}$ , where r = radius of the circle

So,

$256\pi = \pi r^{2}$

Cancelling π from both the sides,

$=> r^{2} = 256$

$=> r = \sqrt{256} = 16$

The radius of the circle = 16 in.

When the radius is multiplied with 4 , new radius = 16×4 = 64 in.

New Area = $\pi (64)^{2} =4096\pi \: in^{2}$

Help asap please i don't know the answer lol

Sveta_85 [38]

Answer:

Step-by-step explanation:

The parallel line BC divides the sides AD and AE in proportion, that is

$\frac{AB}{BD}$ = $\frac{AC}{CE}$ , that is

$\frac{2}{3}$ = $\frac{AC}{4}$ ( cross- multiply )

3AC = 8 ( divide both sides by 3 )

AC = $\frac{8}{3}$ = 2 $\frac{2}{3}$ , hence

AE = AC + CE

= 2 $\frac{2}{3}$ + 4 = 6 $\frac{2}{3}$ → H

Express the following repeating decimal as a fraction in simplest form.

Ivenika [448]

Answer:

$0.\overline{369} = \frac{41}{111}$

Step-by-step explanation:

x = 0.369369369...

10x = 3.69369369...

100x = 36.9369369...

1000x = 369.369369...

1000x - x = 369

999x = 369

$x = \frac{369}{999} \\\\x = \frac{123}{333}\\\\x = \frac{41}{111}$
