The area of a regular hexagon inscribed in a circle with radius 2 is . Round your answer to the nearest tenth.
Verdich [7]

Answer:

10.4 to nearest tenth.

Step-by-step explanation:

If we draw lines from the centre of the circle to each vertex of the hexagon we get 6  equilateral triangles  of side length 2.

Altitude of each triangle  = sqrt(2^2 - 1^2)

= sqrt3.

So the area of 1 triangle = 1/2 * 2 * sqrt3

= sqrt3

Therefore the area of the hexagon = 6 * sqrt3

= 6sqrt3

= 10.3923

Using complete sentences, explain how to find the quotient of 8 2/3 ÷ 1 3/5. Make sure to include the quotient in your answer.​
White raven [17]

Answer:

6 over 1/24

Step-by-step explanation:

You can find the quotient of 9 2/3 divided by 1 3/5 by first making the two terms into improper fractions.

To make the improper fractions, you can turn 9 2/3 into 29/3 by multiiplying 9 by the denominator (bottom number in fractions)  and adding that to the numerator of 2 which gives 29.

1 3/5 can turn into 8/5.

Then you can divide using a simple trick of first organizing the data.

Currentlly it should be

29/3 divided by 8/5

Then you can flip the second fraction over.

29/3 divided by 5/8

Then you change the sign into multiplication.

29/3 times 5/8

Then you multiply like normal.

29 times 5 over 3 times 8

145 over 24

You can simplify now

6 over 1/24

Hope this helps!
