If the minute hand is 6 inches long what is a good estimate of the circumference of the clock?
The minute hand will usually be about 1/8 inch from the edge of the clock face. The hand plus 1/8 inch is the radius, so the diameter of the clock face would be 12-1/4 inches (diameter is radius x 2). The formula for finding circumference is Pi x D, where Pi = 3.1416 and the D is the diameter. Using the formula C = Pi x D: C = 3.1416 x 12.25 = 38.4846 inches would be a good estimate of the circumference of the clock face.

How far does the tip of the minute hand of a clock move in 35 minutes if the hand is 9 inches long?
Assuming the 9 inches is from the pivot point to the tip of the minute hand: In 1 hour = 60 minutes the tip of the minute hand sweeps out the circumference of a circle with radius 9 inches. In 35 minutes, it sweeps out a fraction on 35 minutes/1 hour of this. The circumference of a circle is given by circumference = 2 × π × radius Therefore the tip of the minute hand moves: length = 35/60 × 2 × π × 9 in → length = 21/2 π in = 10½ π in ≈ 33.0 in

What is the circumference of a clock with a 4.5ft radius?
9 Pi is the circumference.
A circular clock has an area in square inches that is equal to three times its circumference in inches What is the diameter of the clock?
pi r2 = 3 x 2 pi r Divide each side by pi r, giving r = 3 x 2 so radius is 6 inches and diameter 12 in.
How far does the tip of the minute hand of a clock move in 35 minutes if the hand is 4 inches long?
It moves 35/60 of a circle. Circle is circumference 2 pi r. r=4 so that's 8pi So, we have 8x35/60 pi = 280/60 pi = 14/3 pi, or approximately 14.66 inches
What is the circumference of the clock if the radius of a clock face is 8.5 centimeters?
2 chainz
What is the circumference of a clock with a diameter of 8?
25.12. Circumference= pi (3.14) multiplied by 8 (diameter.)
What is the time period of the minute hand on a clock?
The time period of a nimute hand on the clock is one minute since it takes a minute for it to complete one oscillation, ie., one complete cycle of the clock.
How you can meaure 3 minute using 7 minute and 11 minute sand clock without using any electric instruments?
Start both sand clocks off at the same time. When the 7-minute clock runs out turn it over. When the 11-minute clock runs out turn it over. START TIMING. When the 7-minute clock next runs out it will have been 3 minutes.
What is the speed of a clock's second hand?
A clock's second hand makes one complete revolution each minute. Thus, by definition, it is rotating at one revolution per minute or one RPM. That's its "rotational velocity" and it is the same no matter how big or small the clock might be. The actual velocity that the tip of the second hand might trace out as it revolves around the center of the clock will vary with the length of the second hand. The longer the hand, the faster the tip moves around the circumference.
If the minute hand on a clock is 4.5 centimeters long what distance does the tip travel in one complete rotation?
Minute hand is 4.5 cmTip of the minute hand completes one complete circle with radius 4.5 cmhence the distance traveled by the tip of minute hand is(2 * 22/7 * 4.5 ) ( circumference of the circle 2 pi R )
