1 mile =1.60934km
So the have travelled about 1 mile.
To get the surface area of a sphere, we need to have the radius. We are given the circumference. The circumference formula is C=2πr. We need to solve for r.
23 = 2πr
r=3.66
The calculation for surface area is <span>A = 4πr^2.
</span>A = 4<span>π(3.66)^2
Solve for A.
A= 168 cm^2.</span>
The answer is D for sure :) y = 2^(1) =
y = 2 which is a plot on the graph.
The correct answer is: [C]: <span>4(a + b + 2) .
