Answer:
Area: 201.06
Circumference:50.26
Step-by-step explanation:
Area of a circle: pi*r^2
8^2=8*8=64
64*pi=201.06193 Rounded to the neares hundredth=201.06

Step-by-step explanation:
<em>it is a right angle triangle</em>
30square =14square +x square
900=196+xsquare
900-196=xsquare
704=xsquare
root704=x
26.532=x
90+26.532=63.468
180-63.468=116.532degree
