Answer:
the area is about 452.39
Step-by-step explanation:
A circle is painted in the center of a basketball court. If the diameter of the circle is 12 feet, what is the approximate amount of space inside of the circle? (Use 3.14 as an approximation of pi.)
A=πr2=π·122≈452.38934
Answer:
-17.25
Step-by-step explanation:
So first you add -8.3 and -7.7, from there you get -16.
-1 1/4 would be -1.25 as a decimal. So all you do is add -16 and -1.25 and you get -17.25 as your answer
Answer:
( About ) 1,099 pounds
Step-by-step explanation:
The force required to keep this truck from rolling down the hill is opposed by the force of friction, comparative to the 2600 pounds of force against this friction. It should be that this opposing force is at work more towards the bottom of this hill, and thus the question asks the magnitude of latter force to keep this truck idle -
|| F || = sin( 25 ) * ( Fg ) = sin( 25 ) * ( 2600 lb ) = ( About ) 1098.80748 pounds
<u><em>This can be rounded to a solution of 1099 pounds</em></u>
Answer:
Step-by-step explanation:
a. Area is calculated by summing the areas of the prism's individual surfaces.
#First, calculate the areas of the right-angled surfaces:
#We then find the areas of the rectangular surfaces:
#We sum the areas to find the total surface areas:
Hence, the prism's surface area is

I would find it easiest to reduce the number to minutes, like this: 500 in 20 minutes would be 500 divided by 20 = 25 pteradactyls /min.
There are 90 minutes in an hour and a half, so 25 x 90 = 2,250 pteradactyls in 1 1/2 hours.
