lol you deleted my answer loser
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
7π/4 radians = 315°, Quadrant IV
sin(315°) = -√2/2
cos(315°) = √2/2
tan(315°) = -1
Step-by-step explanation:
Area= length * height
21*9 = 189cm^2
Hello!
Here we have s=r*thetha and s is arc length which is what you want here. Also r is radius and theta is in radians only! So given your values we have
s=3.5/2*(20revs)*2pi
(because 2pi is one rev in radians)
s=1.75*40pi = 70*pi for an exact answer. Or 70*pi= 220ft
Hope this helps! Any questions please ask!!
Thank you!!
