Answer:
(a) 4.00×10^7 m
(b) 5.10×10^14 m^2
(c) 1.083×10^21 m^3
Step-by-step explanation:
Put the given value of radius into the various formulas and do the arithmetic. Your scientific calculator can show you the results in scientific notation.
C = 2πr = 2π·6.37×10^6 m ≈ 4.00×10^7 m* . . . circumference
A = 4πr^2 = 4π(6.37×10^6 m)^2 ≈ 5.10×10^14 m^2 . . . area
V = (4/3)πr^3 = (4/3)π(6.37×10^6 m)^3 ≈ 1.083×10^21 m^3 . . . volume

The answer is 20 hours.
If window washing crew can finish 10 windows per hour. Let;s solve how many hours will it take him to finish 200 windows.
=> 200 / 10 = 20 hours,
Although we are not outrightly given with the illustration showing lines AB and CD, we may determine if they are perpendicular based on their slopes.
For pair of perpendicular lines, the product of their slopes should be equal to -1. This means that the slopes are multiplicative inverses of each other. We then, inspect each choice.
(a) (5/3)(-3/5) = -1
(b) (4/3)(-3/4) = -1
(c) (5/3)(-3/4) = -5/4
(d) (4/3)(-3/5) = -4/5
The answer could either then be a or b.
