The area of the circle would be 81π.
Square roots are numbers.
if you multiply a number by itself then it is a square number. if you are looking to find a square root of a number, a square root is finding the number that was squared (multiplied by itself) to make the other number. For example,
the square root of 4 = 2
2×2 =4
Another example, square root of 64 is 8
8×8 is 64 :)
Answer:
25
Step-by-step explanation:
Answer:
first side=40
second side=20
third side=22
Step-by-step explanation:
LET THE SIDES OF THE TRIANGLES BE y
Perimeter=82
first side=2 x y = 2y
second side=y
third side=2 +y
2y + y + 2 + y=82
4y+2=82
4y= 82-2
4y=80
y=80/4
y=20
first side=2y=2(20)=40
second side=y=20
third side= 2 + y= 2 + 20 = 22
Both 8,15,17 and 15,20,25 will form a right triangle
If you need help with these types of problems just go into google and search Pythagorean theory silver and plug in 2/3 side lengths and if the outcome equals the third number, then that means that the side lengths make a right triangle
