Answer:

11.1

Step-by-step explanation:

Here, we want to get EF

To do this, we use the appropriate trigonometric ratio

we have the side facing the right angle as the hypotenuse

the measure of this is 18

The side facing the angle 38 is EF

This is the opposite to angle 38

The ratio of the opposite to the hypotenuse is equal the sine

sin 38 = EF/18

EF = 18 sin 38

EF = 11.1

Y equals 8<br> X equals 575<br><br> Solve for slope intercept <br><br> y equals mx + b
zhannawk [14.2K]

y = 8

x = 575

We want to solve for b in the slope-intercept form y = mx + b.

To complete this problem, we need the value of m, the slope. If you know m, then just plug into y = mx + b this way:

8 = 575m + b

Answer:

16682.7 cm³

Step-by-step explanation:

The total volume is the volume of the cone plus half the volume of a sphere:

V = ⅓ π r² h + ½ (4/3 π r³)

V = ⅓ π r² h + ⅔ π r³

V = ⅓ π r² (h + 2r)

Given that r = 4.15 cm and h = 10.2 cm:

V = ⅓ π (4.15)² (10.2 + 2×4.15)

V ≈ 333.65

The volume needed for 50 cones is therefore:

50V ≈ 16682.7 cm³
