Asphere has a surface area of 9244 square feet what is the radius of the sphere use 3.14 for pi and round to the nearest hundredth

By definition, the surface area of the sphere is given by:
 A = 4 * pi * r ^ 2
 Where,
 r: sphere radio
 Clearing r we have:
 r ^ 2 = A / (4 * pi)
 r = root (A / (4 * pi))
 Substituting values we have:
 r = root (9244 / (4 * 3.14))
 r = 27.12908515
 round to the hundredth:
 r = 27.13 feet
 
 The radius of the sphere is:
 r = 27.13 feet

10 will be the number of adult tickets and 11 will be the number of children tickets. i hope i could ! good luck : )
