Answer:
62.8
Step-by-step explanation:
The radius of the blue circle is 5+5=10
the circumference is 2πr so
2(3.14)10= (using 3.14 as π)
20(3.14)=
62.8
Answer:
x = 15
Step-by-step explanation:
Since it a right triangle we can use the Pythagorean theorem
c² = a² + b²
c = hypotenuse
a, b = legs
plug in the values
x² = 9² + 12²
solve
x² = 81 + 144
x² = 225
x = 15

This can also be written as A = s^2 and the area would be 49 with a side length of 7.
In order to find this, you can stick 7 into the area equation.
A = s^2
A = 7^2
A = 49
