Answer:
The answer is A. 17π
Step-by-step explanation:
In order to get this answer I looked at the formula for the circumference of a circle and the formula is c = 2πr (c being circumference, r being radius, π being pie) So if the bigger circle's circumference is 68π then you need to divide 68 by 2 to figure out the radius.
So 68/2=34 and the radius of the smaller circle is 1/4 of 34 which is 8.5.
Then you multiply the radius (8.5) by 2 to get 17π for your final answer.
So happy to help! Please let me know if I was wrong or right! :)
The answer is b foo im pretty sure
Answer:
x ≈ 17.14
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan35° = = ( multiply both sides by x )
x × tan35° = 12 ( divide both sides by tan35° )
x = ≈ 17.14 ( to the nearest tenth )
Answer:
50%
Step-by-step explanation:
because the whole circle is 100% and half of it is shaded
so.... 50%
Patel needs to solve the quadratic equation. The steps in the solution are shown below:
8x² + 16x +3 =0
Transpose 3, we have:
8x² + 16x = -3
Factor out 8, we have:
8 (x² + 2x) = -3
Divide both sides by 8, we have:
x² + 2x = -3/8
Add 2 in both sides, we have:
x² + 2x +2= -3/8 +2
(x+`1)² = -3/10
