We can use the formular-
12.6
to relate a ball's surface area S (in square Inches) to its radius r (in inches). Suppose a ball has a surface area of 226.8
square Inches. What is its radius?
Round your answer to the nearest tenth

Respuesta :

Answer:

r = 4.24 inches

Step-by-step explanation:

Given that,

The surface area of the ball, A = 226.8 sq inches

The formula for the surface area of a sphere is given by :

[tex]A=4\pi r^2[/tex]

Where

r is the radius of the ball

[tex]r=\sqrt{\dfrac{A}{4\pi}} \\\\r=\sqrt{\dfrac{226.8}{4\pi}} \\\\r=4.24\ inch[/tex]

So, the radius of the ball is 4.24 inches.
