This is an application of the pythagorean theorem.
c^2 = h^2 + b^2
c = 190
b = 102.5
h = ???

190^2 = h^2 + 102.5^2
16100 = h^2 + 10506.25
36100 - 10506.25 = h^2
25593.75 = h^2
sqrt(25593.75) = h
159.98 = h

The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

ryzh [129]

Answer:

The area of the clock $= 315.41\ inch^{2}$

Step-by-step explanation:

We have been given the face of the clock that is $63\ in$

So that is also the circumference of the clock.

Since the clock is circular in shape.

So $2\pi(r)=63\ inch$

From here we will calculate the value of radius $(r)$ of the clock that is circular in shape.

Then $2\pi(r)=63\ inch =\frac{63}{2\pi} = 10.02\ in$

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now $\pi (r)^{2}=\pi(10.02)^{2}=315.41\ in^{2}$

So the area of the face of the clock = $315.41\ in^{2}$

A car can travel 30 miles on a gallon of gas and had a 20 gallon gas tank. Let g be the number of gallons of gas the car has in

Fudgin [204]

Answer:

The domain is the number of gallons and the range is the distance traveled.

Since the car can travel 30 miles one gallon of gas, we multiply by 12 to get the distance the car can travel in 12 gallons of gas.
