Answer:
The area of the pizza with a diameter of 18 inches is 254.34 inches.
Step-by-step explanation:
The formula to find the area of a cirlce is A = pi x r^2 or pi times radius squared.
Second, we need to find our radius. To find the radius we need to divide the diameter by 2 to get the radius. In this case; 18 divided by 2 is 9.
Then, we need to plug the radius in the formula:
A = 3.14 x 9^2
9 squared or 9 times 9 equals 81
Next, multiply 81 by 3.14 and you get 254.34
Lastly, add the units of measurement, which would be inches.
Frequency=(speed of sound)/(wavelength)
that means
wavelength =(speed of sound )/(frequency)
speed of sound=344 m/s
4.
frequency=587. 33 Hz
thus
wavelength=344/587.33
=0.586 m
5.
frequency=493.88 nHz
thus
wavelength=344/493.88
=0.69653 m
6. Frequency= 698.46 Hz
wavelength= 344/698.46
wavelength=0.4925 m
9. Frequency =783.99 Hz
wavelength=344/783.99
wavelength=0.439 m
You divide 91/14 to get w=6.5.
