Answer:

<h3>            It's about 365 cm²</h3>

Step-by-step explanation:

2×πr² + 2πr×h =

= 2×π×4² + 2π×4×10.5 =

= 32π + 84π =

= 116π ≈

≈ 364.42 cm²

The area of a circle is 100 π.what is the lenght of the side of a tegular hexagon inscribed in a circle.
yawa3891 [41]
This logic, geometric logic at that.

First find the radius of the circle.

area = \pi {r}^{2} \\
We find the radius by a little algebraic manipulation.

area = \pi {r}^{2} \\ \sqrt{ \frac{area}{\pi} } = r \\ \sqrt{ \frac{100\pi}{\pi} } = r \\ radius = 10

Answer:

The height of the hexagon is 10 units (whatever the units are, every measurement needs units). All the sides of a polygon are equal, and it's a regular hexagon, which is a polygon. It's simple thinking, mostly people get into trouble when they over think it

Would I distribute or foil first -2(b-2)(b-2)
7nadin3 [17]
You would distribute the -2 and the first b-2
-2xb= -2b
-2x-2= 2
So it would now be -2b - 2 (b-2)

A triangle has one leg that is 8, one leg that is 15 and a hypotenuse that is 20. Is it a right triangle?
gregori [183]

Answer:

No

Step-by-step explanation:

A^2+b^2=c^2

8^2+15^2=20^2

64+225=400

289=400

289 does not equal 400 so it is not a right triangle

Explanation how solve step by step 2/7m-1/7=3/14
Drupady [299]

Answer:

m = 25/28

Step-by-step explanation:

It's best to enclose fractional coefficients inside parentheses to eliminate ambiquity:   2/7m-1/7=3/14 => (2/7(m - (1/7) = (3/14).

The LCD is 14; each of the denominators {7, 14} divides evenly into 14.  Hence our equation becomes

(4)(m - 1/7) = 3

... after multiplying every term by 14.

Let's multiply each side by 7 to eliminate the remaining fraction:

4(7m - 1) = 21, or

28m - 4 = 21, or

28m = 25.

Hence, m = 25/28.
