A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
<span>ω = 5 revolutions per minute. 1 minute = (1/60) hour. </span>
<span>= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14 </span>
= 600*3.14 = 1884 radians / hour
<span>but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile </span>
Linear velocity, v = ωr
<span> v = 1884 radians / hour * (10/5280) mile </span>
v ≈ 3.568 miles / hour<span />
Yes the Sudafed area is equal
Okay follow these patterns and you will always get your answer
Cone = (13)πr2h, where r is the radius and h is the height.
Cube = s2, where s is the length of the side.
Cylinder = πr2h, where r is the radius and h is the height.
Rectangular prism= l×w×h, where l is the length, w is the width and h is the height.
Sphere = (43)πr3, where r is the radius.
ANSWER: (D) 904.78 cm^3
Answer:
Reflection across the A axis
It’s a 90 degree angle. So the equation so be 28+2x =90 and find x from there.
28+2x=90
-28 -28
2x= 62
x=31
