volume of a sphere = 4/3 *pi * r^3
3/4 * pi = 4/3 *pi * r^3
divide each side by pi
3/4 = 4/3 * r^3
multiply each side by 3/4
3/4 * 3/4 = r^3
9/16 = r^3
take the cube root of each side
r = (9/16) ^ (1/3)
No ou are wrong because 8 tenths = 80 while 5 hundredths= 500 the right answer is gonna be 80-500= -420
3x - 5y = 27
-3x -12y = 24
-17y = 51
/-17 /-17
y = 3
x + 4(3) = -8
x + 12 = -8
-12 -12
x = -20
(-20, 3)
Answer: 8x^4.5, 4x^3
Step-by-step explanation:
