Is this two separate equations?
Answer:

Step-by-step explanation:
you first need to change the mixed number to an improper fraction

then multiply the second fraction by 2 so that the denominator is the same in both fractions


So we know that the area of a full circle is pi multiplied by radius squared
But for a semicircle the area is pi multiplied by radius squared divided by two
So, we do 3.14*3^2/2
Which is 14.13
Even though it may look like the option is E the real answer is that the variables are invesely related. So your answer will be D
Answer:
4.66
14÷ 3 = 4 r 2
add 0 to 2 ( this attracts a decimal point in your answer)
20 ÷ 3 = 6r 2
and = 4.66
