Answer:
Step-by-step explanation:
step 1
Find the surface area
we know that
the surface area of a sphere is equal to
substitute
substitute the approximate value of pi (3.14)
step 2
Find the volume
The volume is equal to
substitute
Pi IS an: irrational number, a real number
Pi is NOT a: whole number, natural number, rational number, integer
tan 52 = 180/a; a = 180/tan 52
tan 43 = 180/b; b = 180/tan 43
you need to calculate, a-b = 180/tan 52 - 180/tan 43
substitute the value of tan thetas, and calculate it simply...
