Step-by-step explanation:
area of circle= πr²
3.14×7×7
153.86 is the required area
The answer is... Hope this helped
Answer:
39.9
a/sinA = c/sinC
a/sin(77) = 16/sin(23)
a = sin(77) × 16/sin(23)
a = 39.89935764
-1/2
We can find the slope if we are given two points
m = (y2-y1)/(x2-x1)
= (4-8)/(4 - -4)
= (4-8)/ (4+4)
= -4/8
= -1/2
