Step-by-step explanation:
the answer is in the attachment
Surface area of a sphere = 4πr²
Surface area of the sphere = 4π(0.8)² = 8.0 ft²
Volume of a sphere = 4/3 πr³
Volume of the sphere = 4/3 π(0.8)³ = 2.1 ft³
Answer: Surface area = 8.0 ft² and volume - 2.1 ft³ (Answer C)
108 is 144% of 75! Hope I helped. :)
This equation states that x equals -1. So you plug in -1 to all the x's and solve.
So, your equation would be f(-1) = (-1)(2) - 81
So, f(-1) = -2 - 81
Then, this means that f(-1) = -83
So........
f(-1) is equal to -83
