The size of a bicycle is determined by the diameter of the wheel. You want a 22-in bicycle for your birthday. What is the area o

Answer:

The Area of the bicycle wheel=380.182 square inch

Step-by-step explanation:

The formula for calculating the area of a wheel is given by;

A=(πd²)/4

A=Area of the wheel to be calculated

Where π (pie)=3.142,

The wheel size is usually denoted by its diameter (d)

d=diameter of the wheel=22 inches

with the values of π and d given, we can plug them in the formula for calculating Area to determine the area of the bicycle wheel

Substituting the values for π and d in the formula;

A=(πd²)/4=(3.142×22²)/4=380.182 in²

The Area of the bicycle wheel=380.182 in²

A machining operation produces bearings with diameters that are normally distributed with mean 3.0005 inches and standard deviat
padilas [110]

Answer:

5%

Step-by-step explanation:

The 68-95-99.7 rule for the Normal distribution is an empirical rule that remind us the percentages of data that falls between the mean ± 1, ± 2 and ± 3 standard deviations.

That is to say, if the mean is m and the standard deviation s, roughly speaking 68% of the data falls between  [m-s, m+s], 95% between [m-2s, m+2s] and 99.7% between [m-3s, m+3s].

Since the mean is 3.0005 and the standard deviation is s=0.0010, 2s=0.0020, 95% of the data should fall between [3.0005-0.0020, 3.0005+0.0020] and 5% outside this interval. So <em>around 5% of total production will be scrap</em>.

What is the area of a sector with a central angle of 8 π/11 radians and a radius of 7.2 ft? use 3.14 for π and round your final
coldgirl [10]

Answer:

59.19 ft^2

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

we have

r=7.2\ ft

\pi =3.14

substitute

A=(3.14)(7.2)^{2}

A=162.78\ ft^2

step 2

we know that

The area of a circle subtends a central angle of 2π radians

so

using proportion

Find out the area of a sector with a central angle of 8 π/11 radians

\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2
