Answer:
r=4
Step-by-step explanation:
Area of a circle is
A = pi* r^2
We know the area and 3.14 = pi
50.24 = 3.14 * r^2
Divide each side by 3.14
50.24/3.14 =3.14 /3.14 *r^2
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
Answer:
an angle greater than 180° and less than 360°.
Step-by-step explanation:
2x(x+4)-1(x+4)
2x^2+8x-x-4
2x^2+7x-4
If it is a right triangle and AC is the hypotenuse, then AC is 5.
This is a Pythagorean Triple 3-4-5
