Answer:
x=-5.143 or ![-\frac{72}{14}](https://tex.z-dn.net/?f=-%5Cfrac%7B72%7D%7B14%7D)
Step-by-step explanation:
Subtract 75 from 3 and you get -72
-72=4x
x=-5.143
The radius of circle is 41.76 cm
<u><em>Solution:</em></u>
Given that, 70° arc of a circle has a length of 51 cm
To find: Radius of circle
<em><u>The formula for arc length when angle given in degrees is:</u></em>
![Arc\ Length = 2 \pi r \times \frac{\theta}{360}](https://tex.z-dn.net/?f=Arc%5C%20Length%20%3D%202%20%5Cpi%20r%20%5Ctimes%20%5Cfrac%7B%5Ctheta%7D%7B360%7D)
Where,
"r" is the radius of circle and
is the central angle in radians
From given,
Arc length = 51 cm
= 70 degrees
<em><u>Substituting the values in formula,</u></em>
![51 = 2 \times 3.14 \times r \times \frac{70}{360}\\\\51 = 6.28 \times r \times 0.194\\\\51 = 1.2211r\\\\r = \frac{51}{1.2211}\\\\r = 41.76](https://tex.z-dn.net/?f=51%20%3D%202%20%5Ctimes%203.14%20%5Ctimes%20r%20%5Ctimes%20%5Cfrac%7B70%7D%7B360%7D%5C%5C%5C%5C51%20%3D%206.28%20%5Ctimes%20r%20%5Ctimes%200.194%5C%5C%5C%5C51%20%3D%201.2211r%5C%5C%5C%5Cr%20%3D%20%5Cfrac%7B51%7D%7B1.2211%7D%5C%5C%5C%5Cr%20%3D%2041.76)
Thus the radius of circle is 41.76 cm
I strongly believe that the answer is d. But I really believe that is the answer
