A map with a scale of 2:in:350 mi shows two cities to be 6 inches apart. How many miles apart are the cities?
Serhud [2]

Answer:

1050miles.

Step-by-step explanation:

since every 2 inches=350 miles, then 6 inches= 3(350miles)

since 6/2=3.

or you can think of it this way:

there are 3 2-inches in 6 inches, and every 2 inches, it's 350s miles.

350+350+350=1050miles.

Find the volume of a cylinder with a radius of 3 cm and a height of 7 cm.
yuradex [85]

Answer:

197.92 cm

Step-by-step explanation:

The formula to find volume for a cylinder is V=πr^{2}h

The problem gave you the height (h): 7cm and the radius (r): 3cm and pi (π) is a constant that will automatically insert when you use the "π" button in a calculator

Now that you know that you have all your variables, you can now plug them into your formula.

V=π3^{2}7

Next, solve the equation.

V=π(9)(7)

V=π(63)

V=197.92cm

Hope this helped! :)
