A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?

goldenfox [79]

Answer:

Step-by-step explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

Answer:

Hey buddy, here is your answer. Hope it helps you.

Christopher and Edward were painting wagon wheels for the school play. The pictures show how much of the wheels they painted. Ho

Marina CMI [18]

Using fractions, it is found that $\frac{43}{45}$ of a wheel still needs to be painted.

On the first wheel, 4 of the 9 equal parts have been painted, that is, $\frac{4}{9}$ of the wheel has been painted, hence $\frac{5}{9}$ has not been painted.

On the second wheel, 6 of the 10 equal parts have been painted, that is, $\frac{6}{10} = \frac{3}{5}$ of the wheel has been painted, hence $\frac{2}{5}$ has not been painted.

The total fraction that still has to be painted is:

$\frac{5}{9} + \frac{2}{5} = \frac{25 + 18}{45} = \frac{43}{45}$

$\frac{43}{45}$ of a wheel still needs to be painted.

Solve 2x2 − 8x = −7.

leva [86]

$\sf 2x^2 - 8x = - 7 \\ \\ Subtract \ -7 \ from \ both \ sides \ of \ the \ equation. \\ \\ 2x^2 - 8x - (-7 ) = - 7 - (-7) \\ \\ 2x^2 - 8x + 7 = 0 \\ \\ Use \ quadratic \ formula \ a = 2, b = -8, c = 7 \\ \\ x = \dfrac{- b \pm \sqrt{b^2- 4ac} }{2a} \\ \\ \\ x = \dfrac{-(-8) \pm \sqrt{(-8)^2 - 4 (2) (7) } }{2(2)} \\ \\ x = \dfrac{8 \pm \sqrt{8} }{4} \\ \\ x = 2 + \frac{1}{2}\sqrt{2} \ or \ x = 2 + \frac{-1}{2} \sqrt{2}$
