If I have a cylinder, the radius is 9.3 ft and the height is y, the volume of the whole thing is 3000ft, then what does y equal?
disa [49]

Answer:

Step-by-step explanation:

r = 9.3 ft

h = y ft

Volume = 3000 ft

πr²h = 3000

3.14 * 9.3 *9.3 * y = 3000

y = \frac{3000}{3.14*9.3*9.3}\\\\

y = 11.05 ft

In triangle ABC, angles A and angle B are complementary, where cos A = 0.5.
Valentin [98]

Answer:

<h3>∴∠B=30°</h3>

Step-by-step explanation:

Complementary:

Two angles is said to complementary when the sum of two angles is 90 degree.

Given that,

∠A and ∠B are complementary.

Then,  ∠A + ∠B = 90°

Cos A = 0.5

\Rightarrow A=cos^{-1}(0.5)

\Rightarrow A=cos^{-1}(cos \ 60^\circ)

\Rightarrow A=60^\circ

Since

 ∠A + ∠B = 90°

⇒ 60°+ ∠B = 90°      [ plug ∠A= 60°]

⇒∠B=90°-60°

⇒∠B=30°

<h3>∴∠B=30°</h3>
