Answer:
109.9
Step-by-step explanation:
diameter of circle(d)=35
perimeter of circle(p)=?
we know,
p=pi d
=3.14×35
=109.9
The pens were 20% off of the original price
We first know that 66 as a decimal is well 66. Now, 2/3 as a decimal would be 66.666666 and so on on. Therefore, 66 and 2/3 as a decimal is 66.66666 and so on.
So divide 20 into 3
then u do wat u do 4 the rest
Answer:
1056 radians/min
Step-by-step explanation:
We can convert the linear speed to inches per minute to help with finding the angular speed.
(12 mi/h) = (12 mi)(5280 ft/mi)(12 in/ft)/((1 h)(60 min/h))
= (12×5280×12/60) in/min = 12,672 in/min
Each radius-length represents 1 radian of arc of the wheel. The radius is half the diameter, 24 in/2 = 12 in, so the angular speed is ...
(12,672 in/min)/(12 in/radian) = 1056 radians/min
