377. Dawn wants to compare the volume of a basketball with the

olchik [2.2K]

Answer:

$V = \frac{4}{3} \pi R^{3}$ and

$v = \frac{4}{3} \pi r^{3}$

Step-by-step explanation:

Dawn wants to compare the volume of a basketball with the volume of a tennis ball.

Now, if the radius of the basketball is R and that of the tennis ball is r, then the formula that can be used to determine the volume of each ball will be

$V = \frac{4}{3} \pi R^{3}$ and

$v = \frac{4}{3} \pi r^{3}$

Now, dividing V by v we can compare the volume of the basketball and the tennis ball. (Answer)

Use a half-angle identity to find the exact value of sinPi/8

stellarik [79]

Answer:

sin(π/8) = (1/2)√(2-√2)

Step-by-step explanation:

Using the half-angle formula ...

$\sin{\dfrac{\theta}{2}}=\sqrt{\dfrac{1-\cos{\theta}}{2}}$

We can let θ = π/4 and simplify the result as follows:

$\sin{\dfrac{\pi}{8}}=\sqrt{\dfrac{1-\cos{(\pi/4)}}{2}}=\sqrt{\dfrac{1-\dfrac{\sqrt{2}}{2}}{2}}=\sqrt{\dfrac{2-\sqrt{2}}{4}}\\\\=\boxed{\dfrac{1}{2}\sqrt{2-\sqrt{2}}}}$
