Answer: A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.

What is the phase shift of y = sin(1/2 x - pi/2)?

meriva

Answer:

π

Step-by-step explanation:

The standard form of the sine function is

y = a sin(bx + c)

where a is the amplitude, period = $\frac{2\pi }{b}$ and

phase shift = - $\frac{c}{b}$

here b = $\frac{1}{2}$ , c = - $\frac{\pi }{2}$

phase shift = - $\frac{-\frac{\pi }{2} }{\frac{1}{2} }$

= $\frac{\pi }{2}$ × 2 = π

A honeydew melon is shaped like a sphere with a diameter of 8 inches. Which value is closest to the volume of the melon?

Aleksandr [31]

Answer:

The volume of sphere = 268.08

Step-by-step explanation:

Below is the calculation for the volume of melon (sphere).

Given the diameter of the sphere is = 8 inches

Now find the radius by dividing the diameter by 2 = 8/2 = 4 inches

Now use the below formula to find the volume.

The volume of sphere = $\frac{4}{3} \times \pi \times r^{3}$

The volume of sphere = 268.08
