The center of the circle is (-4,6). the circle passes through the point (-2,3). what is it’s radius

Nadusha1986 [10]

Answer:

Radius is 3.6

Step-by-step explanation:

Using Pythagorean Theorem we find the Hypotenuse with the side lengths which are 3 and 2.

The quick equation to solve that would be

$\sqrt{3^2+2^2} =\sqrt{13} = 3.60$

A bicycle wheel has a small pebble embedded in its tread. The bike is set upside down, and the rider accidentally bumps the whee

nikdorinn [45]

Answer:

a) The radius of the wheel is 1) more than 25.0 cm.

b) The radius of the wheel is approximately 40.925556... cm

Step-by-step explanation:

S = rθ is the formula to find the radius of the wheel using the arc and the angle discovered, S being the arc and θ the angle. The angle, however, must be in radians. θ = $\frac{35\pi}{180}$ is used to convert it. So:

θ = $\frac{35\pi}{180}$

θ = $\frac{7\pi}{36}$

S = rθ

25 = r $\frac{7\pi}{36}$

900 = 7 $\pi$ r

r = $\frac{900}{7\pi }$

r = 40.925556... cm

PLEASE HELP AND ILL GIVE BRAINLIEST

stepladder [879]

Answer:

Step-by-step explanation:

Subtract the number with the term both sides ( which is 9)

${x}^{2} + {y}^{2} - 6x + 4y = - 9$

Complete the square for the x terms and y terms.

( To complete the square divide the coefficient term by 2 and square it, then add that product to both sides.)

${x}^{2} - 6x + 9 + {y}^{2} +4y + 4 = - 9 + 9 + 4$

$(x - 3) {}^{2} + (y + 2) {}^{2} = 4$

Take the square root of the right side to find the radius

$\sqrt{4} = 2$
