Remember that the formula for the surface area of a sphere is

. Substitute the given surface area to solve:

. Divide by 4 on both sides:

. Divide by pi on both sides:

. Square root on both sides to find the radius:
Answer:
t = total people
m = men
w = women
w / m = 3 So A) w = 3 * m
B) w = m + 200
multiplying A) by minus 1
A) -w = -3m
B) w = m + 200
Adding the 2 equations
0 = -2m + 200
2m = 200
m = 100 Since there are 200 more women than men then there are
300 women
Total people = 100 + 300 = 400
