The perimeter of a rectangle is 338, if the ratio of the length to the width is 8:5, find the length

1 answer:

4 0

Let the length be 8x and the width = 5x, then
Perimeter = 2(length + width) = 2(8x + 5x) = 2(13x) = 26x
338 = 26x
x = 338/26 = 13

Therefore, length = 8x = 8 x 13 = 104

Find the radius of a sphere with a surface area of 1024π square inches

agasfer [191]

Answer:

Step-by-step explanation:

The formula of a Surface Area of a sphere:

$S.A.=4\pi R^2$

R - radius

We have

$S.A.=1024\pi\ in^2$

Substitute:

$4\pi R^2=1024\pi$ <em>divide both sides by π</em>

$4R^2=1024$ <em>divide both sides by 4</em>

$R^2=256\to R=\sqrt{256}\\\\R=16\ in$
