Answer:
a) r = 12.001
So diameter is d= 2r
d = 2× 12.001
d = 24.002 ft²
b) r = 44.345 yrds
Step-by-step explanation:
Volume of sphere
V = 4/3×pi×r³
a) Putting the values
7234.56 = 4/3 × 3.14 × r³
Simplifying
r = 12.001 ft
b) putting the values in the formula of volume of sphere
20833.3 yards = 4/3 × 3.14 × r³
Simplifying
20833.3 yards = 4.86 × r³
Rearranging the equation
r³ = 20833.3 × 4.186
r³ = 87208.1
r = 44.345 yards
