Answer: 4 units
Step-by-step explanation:
Given : AB is the diameter of a circle.
Then, the central angle for arcADB must be
because the central angle subtended by diameter is
.
The length of arc is given by :-
![L=r\times\theta\\\\\Rightarrow\ 8\pi=r\times2\pi\\\\\Rightarrow\ r=\dfrac{8\pi}{2\pi}=4](https://tex.z-dn.net/?f=L%3Dr%5Ctimes%5Ctheta%5C%5C%5C%5C%5CRightarrow%5C%20%208%5Cpi%3Dr%5Ctimes2%5Cpi%5C%5C%5C%5C%5CRightarrow%5C%20r%3D%5Cdfrac%7B8%5Cpi%7D%7B2%5Cpi%7D%3D4)
Hence, the length of the radius of the circle = 4 units
He has 12 quarters and 15 dimes. 12 x .25=3. 15 x .1 = 1.5
1.5 + 3 = 4.5
