A cartographer is painting a spherical globe whose surface is 326.7 sq. in. What is the maximum radius of the globe that the car

svlad2 [7]

Answer:

$S =4\pi r^2$

And since we know the surface area 326.7 in^2 we can solve for the value of r like this:

$r =\sqrt{\frac{S}{4 \pi}}$

And replacing we got:

$r =\sqrt{\frac{326.7 in^2}{4 (3.14)}}= 5.10 in$

And the best answer would be:

5.1 in

Step-by-step explanation:

For this case we need to use the formula for the surface area of a sphere given by:

$S =4\pi r^2$

And since we know the surface area 326.7 in^2 we can solve for the value of r like this:

$r =\sqrt{\frac{S}{4 \pi}}$

And replacing we got:

$r =\sqrt{\frac{326.7 in^2}{4 (3.14)}}= 5.10 in$

And the best answer would be:
