<span>The volume V of a sphere is four-thirds times pi times the radius cubed.
V=4/3*Pi*Radius^3
Hence the answer is D) 33,493.3 cm^3
V = 4/3 * Pi * 20^3 = 33,493.3 cm^3</span>

Answer:
a)  4(t - r) = 4(6 - 2.5) = 4 x 3.5 = 14
b)  4t - r = (4 x 6) - 2.5 = 24 - 2.5 = 21.5
c)  2(3t - 10) = 2(3 x 6 - 10) = 2(18 - 10) = 2 x 8 = 16
d)  (t - 2)² = (6 - 2)² = 4² = 4 x 4 = 16
e) cannot decipher the equation
f)  6r + t = 6 x 2.5 + 6 = 15 + 6 = 21
