Answer:
22.7604763 degrees
Step-by-step explanation:
Note that the answer is NOT 20 degrees.
She adjusted the ramp to half the original <em>incline</em>
Therefore we have tan 40 = x = 0.839099631.
We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815
Taking the arctan of both sides, we get
y = arctan(0.419549815) = 22.7604763 degrees
769.3= (3.14) r^2 *5
153.86=(3.14) r^2
49= r^2
The square root of 49 is 7
The answer is 7.
Answer:
2261.54 cubic cm.
Step-by-step explanation:
So 1 cm is equal to .52 cubic cm. So if we take 1176 and divide it by .52 we get 2261.538462. Which is a crazy number, so we round. So 1176 cm = 2261.54 cubic cm. I'm pretty sure that this is correct, good luck! ;)
