Answer:
16π square centimeters.
Step-by-step explanation:
The area of a circle is πr².
Here, we are given the diameter, but we just need to divide it by 2 to get the radius.
8/2 = 4
So, the radius is 4 cm.
Now, we can substitute it into the formula to find the area.
π x 4²
π x 16
16π
So, the area of this circle is 16π.
Answer:
Step-by-step explanation:
Ratio of New York boats to total boats = 1:2
The next 18 boats should include 9 from New York.
Step-by-step explanation:
½ [cos(a − b) − cos(a + b)]
Using sum and difference formulas:
½ [cos a cos b + sin a sin b − (cos a cos b − sin a sin b)]
Distribute the negative:
½ (cos a cos b + sin a sin b − cos a cos b + sin a sin b)
Combine like terms:
½ (2 sin a sin b)
Simplify:
sin a sin b
