Answer:
81
Step-by-step explanation:
divide 1296 by 16 to get the answer
product means ___ x ____ = product
since 16 is one of the numbers and 1296 is the product, it looks like this 16x___=1296
Answer:
12n+2
Step-by-step explanation:
w(n)=4n+2
w(3n)=4(3n)+2
w(3n)=12n+2
Answer:
Circumscribed circle: Around 80.95
Inscribed circle: Around 3.298
Step-by-step explanation:
Since C is a right angle, when the circle is circumscribed it will be an inscribed angle with a corresponding arc length of 2*90=180 degrees. This means that AB is the diameter of the circle. Since the cosine of an angle in a right triangle is equivalent to the length of the adjacent side divided by the length of the hypotenuse:

To find the area of the circumscribed circle:

To find the area of the inscribed circle, you need the length of AC, which you can find with the Pythagorean Theorem:

The area of the triangle is:

The semiperimeter of the triangle is:

The radius of the circle is therefore 
The area of the inscribed circle then is
.
