First let's isolate the sin(x) term

4sin(x) - 4 = 0

4sin(x) = 4

sin(x) = 1

Now use the unit circle and you'll see that the only solution in the interval [0,2pi) is x = pi/2

If you want to ignore the restriction and consider all solutions, then x = (pi/2) + 2pi*n where n is any integer

Find the lateral area of the cylinder to the nearest tenth.

vovangra [49]

Answer:

Lateral area of the cylinder = 62.85 cm²

Step-by-step explanation:

Given:

Diameter of cylinder = 10 cm

Radius of cylinder = 10 / 2 = 5 cm

Height of cylinder = 2 cm

Find:

Lateral area of the cylinder

Computation:

Lateral area of the cylinder = 2πrh

Lateral area of the cylinder = 2(22/7)(5)(2)

Lateral area of the cylinder = 2(22/7)(10)

Lateral area of the cylinder = (440/7)

Lateral area of the cylinder = 62.85 cm²

Answer:

9 possible combinations: RGB, RYG, RGB, OYG, OGB, OBP, YGB, YBP, GBP

Step-by-step explanation:

We need to consider The Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Let's see what are the possible combinations:

3+4= 7 so possible 3rd side is 5
