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
On 3 you subract 36-3 on 4 make the fraction a decimal by dividing the numerator by the denominator and then subtract 12 by the decimal you get and I'm pretty sure you should get both your answers.
Simple the answer is: n=14
Answer:
s = -1
Step-by-step explanation:
7 = -10s - 3
==> add 3 to both sides
10 = -10s
==> divide both sides by -10
-1 = s
