Answer:

The area of the resulting cross section is $78.5\ m^{2}$

Step-by-step explanation:

we know that

The resulting cross section is a circle congruent with the circle of the base of cylinder

therefore

The area is equal to

$A=\pi r^{2}$

we have

$\pi=3.14$

$r=10/2=5\ m$ -----> the radius is half the diameter

substitute the values

$A=(3.14)(5)^{2}=78.5\ m^{2}$

There are 7 meters in 279 inches.

There are 2.54 centimeters in 1 inch.
There are 100 centimeters in 1 meter.
The number of inches is given to be 279.
Unit conversion is a multi-step procedure that includes multiplying or dividing by a numerical factor, determining the appropriate number of significant digits, and rounding.
First of all, we need to convert inches to centimeters.
1 inch equals 2.54 centimeters.
279 inches equals 2.54*279 centimeters.
279 inches equals 708.66 centimeters.
Now, we need to convert these centimeters into meters.
Meters in 100 centimeters = 1
Meters in 1 centimeters = 1/100
Meters in 708.66 centimeters = (1/100)*708.66
Meters in 708.66 centimeters = 7.0866
Thus, there are approximately 7 meters in 279 inches.
