Answer:

Option A is correct.

Step-by-step explanation:

The height of the rectangular pack is h1 = 4r

The height of the parallelogram = 2r + the height of equilateral triangles with a side of 2r

The height of equilateral triangle with a side of 2r = (side)/2*√3

=(2r)/2 *√3 = r√3

The height of the parallelogram h2 = 2r+r√3 = r(2+√3)

So,the ratio of h1 to h2 is :

4r : r(2 +√3)

Cancelling r we get

Hence, the ratio is 4 : 2 +√3

Answer:

132 degrees

Step-by-step explanation:

these angles are Alternate interior angles so angle A is congruent to angle B.

5x-18 = 3x+42

-3x -3x

2x-18 = 42

+18 +18

2x = 60

÷2 ÷2

x=30

A=5(30) -18

= 150-18

= 132 degrees

Find the radius of the circle below. Round your answer to the nearest tenth.

Butoxors [25]

Answer:

5.8 cm

Step-by-step explanation:

Area of the shaded sector of the circle = 31.2 cm²

Angle (θ) of the minor sector = 360 - 256 = 104°

Are of sector of a circle is given as, θ/360*πr²

Therefore:

$\frac{104}{360}*3.142*r^2 = 31.2$

$0.29*3.142*r^2 = 31.2$

$0.91*r^2 = 31.2$

Divide both sides by 0.91

$\frac{0.91*r^2}{0.91} = \frac{31.2}{0.91}$

$r^2 = \frac{31.2}{0.91}$

$r^2 = 34.286$

$r = \sqrt{34.286}$

$r = 5.8$ (nearest tenth)
