Answer:
c = 62.83185
a = 314.15927 m²
Step-by-step explanation:
Hey There!
So first thing that we want to do is find the formula for the circumference
where r = radius
we are given the diameter which we can easily convert to radius by dividing by 2
20/2=10
so the radius is 10
now we plug in
So the circumference is equal to 62.83185 m ²
Now to find the area we use the formula
so we can conclude that the area of the circle is 314.15927
Scientific notation for above vLue is :
Equate the divisor to 0
2x-1=0
2×=1
×=1/2
Putting onto the polynomial
f(1/2) = (1/2)³-1/2)²+3(1/2)-2
=-5/8
-8 and 3
