8x-10 = 150
8x = 160
x = 20
RZ = 8x - 10 = 8(20) - 10 = 150
RT = RZ + ZT = 150 + 150 = 300
answer is
C x = 20, RZ = 150, RT = 300

Answer:
the area of the circle is
.
Step-by-step explanation:
We have,
Circumference of a circle is 3π cm
Formula of circumference of a circle is given by :
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
r is radius of circle
![r=\dfrac{C}{2\pi}\\\\r=\dfrac{3\pi }{2\pi}\\\\r=1.5\ cm](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7BC%7D%7B2%5Cpi%7D%5C%5C%5C%5Cr%3D%5Cdfrac%7B3%5Cpi%20%7D%7B2%5Cpi%7D%5C%5C%5C%5Cr%3D1.5%5C%20cm)
Area of a circle is given by :
![A=\pi r^2\\\\A=\pi (1.5)^2\\\\A=2.25\pi\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%5C%5C%5C%5CA%3D%5Cpi%20%281.5%29%5E2%5C%5C%5C%5CA%3D2.25%5Cpi%5C%20cm%5E2)
So, the area of the circle is
.
