Answer:

In a regular hexagon, the length of the radius is the same as the length of a side.

Step-by-step explanation:

A regular polygon is the polygon which have equal sides. Any regular polygon can be considered as a arrangement of the same number of equilateral triangles ad the number of sides.

For example, a regular hexagon ( 6 sized polygon) is made of the 6 equilateral triangles as shown in the image below.

Thus, the radius (which is the distance of the center of the polygon to any corner of it) is equal to the length of a regular polygon as it is composed of equilateral triangles.

So, option C is correct.

The statement that would be considered be as true is "<span>In a regular hexagon, the length of the radius is the same as the length of a side. In addition, a hexagon could be sliced forming triangles that are equilateral therefore having the same length of sides and similar interior angles. </span>

The formula for the surface area, S, of a cylinder, is S = 2tr2 + 2trh, where h is

Answer:

H = 2 S = 50 A = 50.2

Step-by-step explanation:

A=2πrh+2πr2

S = 2tr2 + 2trh

S = 2 (t x r) + (h x 2t) x r Try out ^2 for Radius

S = 2t x r^2 + r x h x 2t Rearrange back and cross out for square^2

S = 6t x 4 + 6t x r x h Cross out for t

S = 6 x 4 + 6 x 2 x h Balance out...

S= 24 + 12 x 2 Find h = 2

S = 36 + 24

S= 50 sq2

A = 50. 2

R = 2

H = 2

Answer:

x = 7

Step-by-step explanation:

The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).

Solving 8x - 36 + 70 + 90 = 180 for x:

8x - 36 = 20, or 8x = 56.

Dividing both sides by 8 yields x = 7.

Answer:

5/8

Step-by-step explanation:

there are 8 slices.

if he and his friends eat 5 pieces, they ate 5 out of 8 pieces.

in maths, we write 5 out of 8 like 5/8

hope this helped, any questions - just ask

good luck,

No, it does not seem reasonable. The quarterly statement reports an increase of $47, so it would be a positive rate of return on the investment instead of a negative rate.
