Answer is #3
add up all the x’s
the complete question in the attached figureLet
A°-----------> <span>the same central angle
</span><span>
For the larger circlelength of larger circle=2*pi*r-------> 2*pi*12-----> 75.36 m
360</span>°<span> (full circle) has a length of------------> 75.36 m
A</span>°-----------------------------------> 16 m
A°=(16)*360/75.36--------> A=76.43°
For the smaller circlelength of smaller circle=2pi*r-------> 2*pi*7.5-----> 47.1 m
360° (full circle) has a length of------------> 47.1 m
76.43°-----------------------------------> X
X=76.43*47.1/360-----> X=10 m ----> length arc of the smaller circle
the answer isthe length arc of the smaller circle is 10 m
Answer:
81 pi centimeters squared
Step-by-step explanation:
Area of circle = πr²
18/2 = 9
π9²
π(9 x 9)
π81
I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.
