Acartographer is painting a spherical globe whose surface is 326.7 sq. in. what is the maximum radius of the globe that the cartographer is painting? use 3.14 for π.
5.1
4.3
26.0
13.1

r=5.1

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

We know the surface area is 326.7

326.7 = 4 * pi * r^2

Divide each side by 4

326.7/4 =  4* pi * r^2/4

81.675  = pi * r^2

Letting 3.14 = pi , divide each side by 3.14

81.675/3.14 = 31.4 r^2/3.14

26.0111465 = r^2

Take the square root of each side

sqrt(26.0111465) = sqrt(r^2)

5.1001124 = r
