Right angle are known as exactly 90 degrees corresponding to a quarter turn.
area = pi times radius squared
area = pi times 5 squared
area = pi times 25
area = 78.54
answer : 78.54 square feet
Answer:
AC=6
Ab=3
BC= 6.708
a^2+b^2=c^2
so 6*6 is 36
3*3 is 9
36+9=45
Square root 45 and you get 6.708 for BC
If you would like to find the product (n + 8) * (n - 2), you can do this using the following steps:
(n + 8) * (n - 2) = n * n - 2 * n + 8 * n - 8 * 2 = n^2 + 6 * n - 16
The correct result would be n^2 + 6 * n - 16.
