Answer:
33,493.3 cm³
Step-by-step explanation:
Volume of a sphere of radius r = V = (4/3)πr³
Here the radius is 20 cm. Therefore, V = (4/3)(3.14)(20 cm)³ = 33,493.3 cm³
The volume of this sphere, to the nearest tenth, is 33,493.3 cm³
Area of a trapezoid = h * (b1+b2/2)
= 10 cm * ((20.75cm + 16.25cm)/2)
= 185 cm²
Therefore the area of the trapezoid is 185 cm²
