guajiro [1.7K]

Answer:

$90\pi\text{ ft/s}\approx282.74\text{ ft/s}$

Step-by-step explanation:

Refer to physics equation $v=\omega r$ , where $\omega$ is angular velocity.

Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:

$\displaystyle 5\text{ rev/min}=5\cdot \frac{1}{60}\cdot 2\pi\approx 0.524\text{ rad/s}$

Now substitute $\displaystyle\omega=\frac{1\pi}{6}$ and $r=9$ into $v=\omega r$ :

$\displaystyle v=\frac{1\pi}{6}\cdot 9=\frac{3}{2}\pi\text{ ft/s}=\boxed{90\pi\text{ ft/s}}$

Your brother eats 1/6th of your birthday pizza. If the pizza has a diameter of 12 inches, what is the area that he ate

Kipish [7]

Answer:

18.84 in^2

Step-by-step explanation:

Area brother ate = 1/6 x area of pizza

a pizza is the shape of a circle. the area of a pizza is equal to the area of a circle

Area of a circle = πr²

r = 12/2 = 6

he diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x 6^2 = 113.04

1/6 x 113.04 = 18.84
