Answer: Area= 459.73cm^2

Step-by-step explanation: Circumference of a circle is 2πr

76=2×3.14×r

r= 76÷(6×3.14)

r=12.10

Area of a circle= πr^2

Area= 3.14×(12.10)^2

Area= 456.73cm^2

Find the angle measure to the nearest degree. <br> cos A = 0.7431<br> How do I do this?
svet-max [94.6K]

Answer:

Step-by-step explanation:

If you are looking for a missing angle measure, you use the 2nd button and the cos button.  Make sure, first off, that your calculator is in "degree" mode by hitting the "mode" button and making sure that the "degree" is highlighed and not the "radian".  Then hit "clear".  Once you know that you are in the correct mode, hit "2nd" then "cos" and you will see this on your screen:

cos^{-1}(

Inside the parenthesis you will enter your decimal, so it looks like this now:

cos^{-1}(.7431

You do NOT have to close the parenthesis, but you can if you want to.  Then hit "enter" to get that the angle that has a cosine of .7431 is 42.0038314 or, to the nearest degree, 42

Pizzazz pizza sells a small pizza for 10.99. it has a diameter of 10 in. what is the pric per sqaure inch
Nookie1986 [14]
Area of a circle = pi * r^2

Radius (r) = ½ * diameter

½ * 10 = 5

A= pi * 5^2

25 * pi = 78.54 sq inches

10.99 / 78.54 = about 14 cents per sq in (13.99)
