What does AC=?<br> Round your answer to the nearest hundredth. <br><br> Please help

faltersainse [42]

Answer: About 3.06

Step-by-step explanation:

We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

cos(θ) = $\frac{adjacent}{hypotenuse }$

cos(40) = $\frac{x}{4}$

0.766 ≈ $\frac{x}{4}$

3.06 ≈ x

x ≈ 3.06

The figure is made up of 2 hemispheres and a cylinder. What is the exact volume of this figure? 126π in.³ 378π in.³ 396π in.³ 64

bogdanovich [222]

The two domes or hemispheres simply have the area of a complete sphere with the same diameter. So the total area is the area of a sphere and a cylinder...

as=(4p3^3)/3, ac=10p3^2

A= 36p+90p=126p in^3
