Arc/(2πr)=α/360
α=360*arc/(2πr)
α=180*arc/(πr), since arc=12 and r=12
α=2160/(9π)°
α=240/π°
α≈76.39° (to nearest one-hundredth of a degree)
in this case, we are looking at a length × width equation. this equation gives you the area of the gym. so the answer is B.
C=2(3.14159...)R
You’re given the circumference, so all you need to do is plug that in and simplify.
36=2(3.14159...)R
36=6.28R
36/6.28=R
R is about 5.73
Answer:
C
Step-by-step explanation:
Given
(3x² + 5x - 8) + (5x² - 13x - 5) ← remove the parenthesis
= 3x² + 5x - 8 + 5x² - 13x - 5 ← collect like terms
= 8x² - 8x - 13 → C
Answer:
2
Step-by-step explanation:
1+1=2
