First step is to find the circumference of the wheel (pi x diameter)
The radius is half of the diameter so 2 x 30 = 60
60 x pi (3.14) = 188.4 centimeters or 1.884 meters
Changing the kilometers into meters, and diving by 3 (to reduce the 3 hours into meter per hour) you'd get the total distance covered is 36,000 meters which equates to 12,000/hour or 200 meters/minute or 3.33 meters/second.
You take 3.33 and divide it by 1.884 which will give you 1.7675
Now you multiply it by the number of degrees of the wheel (which of course is 360) so 1.7675 x 360 = 636.3
Your answer is 636.3 degrees per second.
Answer:
1) 31.5
Step-by-step explanation:
tanA = opp/ adj
tanA = 11.2/18.3
A= arctan(11.2/18.3)
A= 31.468 -> 31.5
The answer is grade point average (GPA)
Answer:
54 cm²
Step-by-step explanation:
Area of Parrelogram= Length×Breadth
You see, if u move the triangles to he other side, you'll get a rectangle. So you can just take the length multiply by the breadth.
Area=9×6=54 cm²
I did not use meters to find the area. I did not use it as the questions already shows the measurement as centimeters, so if I use meters, I will have to convert it to centimeters.
