Oh, dude, you're hitting me with the math questions! So, the circumference of a circle is just π times the diameter, which in this case is 6.5 cm. So, the circumference would be 6.5π cm... but who's really measuring that precisely, right? Like, just round it to a nice number and call it a day.

EzraThe circumference of a circle can be calculated using the formula C = π * d, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 6.5 centimeters, so the circumference would be C = 3.14159 * 6.5 = 20.42 centimeters.

What is the radius of a circle with a 65 inch circumference?
radius = 65/(2*pi) = 10.3450713 inches
What is 40 centimeters x 65 centimeters?
40 cm x 65 cm = 2,600 cm
A diameter of a circle has endpoints P(-10-2) and Q(46) a.)find the center of the circle b.)find the radius. if your answer is not an integer express it in radical form c.)write an eqaution for the ci?
Endpoints of diameter: (-10, -2) and (4, 6)Midpoint which is the center of the circle: (-3, 2)Radius of the circle: square root of 65Equation of the circle: (x+3)^2 +(y-2)^2 = 65
Angular speed and number of revolutions per minute of a car moving at 65 mph and diameter of wheels in 2.5 feet?
There are 728.3 revolutions per minute, and the angular speed is 4576 radians per minute. This is how you get these answers: (a). Revolutions per minute. 1. Find the circumference of the circle. C= piX Diameter. In this case, C=7.8539816 2. Turn 65 mph into minutes/ft. Thus, 5280ft = 1 mile. 65X5280= 343200 ft. per hour. 1 hr = 60 minutes. 343200/60 = 5720 ft. / per minute. 3. Finally, divide. 5720/7.8539816 = 728.29 = 728.3. (b). Angular speed = central angle/time = Theta/t 1. 728.3 rpm. Now, since 1 revolution = 2pi, then, (728.3)(2pi) radians per minute. Your answer should be 4576.043859. Round to 4576 radians per minute, and you are done!!
What country is 100 E and 65 N?
100 degrees east longitude / 65 degrees north latitude is plumb in the middle of northern Siberia, almost but not quite at the Arctic Circle. You don't want to go there.
