In order to solve the formula

in terms of d, you simply have to divide both sides by pi:

The total height of the earring is the sum of the diameters of the circles. Given their circumferences, the diameters are

So, the total height is

It is 45 . Just simply multiply both numbers. You will get the smallest denominator
Answer:
k is the option that makes sense
Y = ln |1 + t - t^3| = (1 - 3t^2)/(1 + t - t^3)
(50+ b)5
= 5* (50+ b) (commutative property)
= 5* 50+ 5* b (distributive property)
= 250+ 5b
= 5b+ 250
The final answer is 5b+ 250.
Hope it helps.
