Calculate the perimeter of a square whose diagonal measures 29 dm.
mojhsa [17]

Answer:

4\sqrt{420.5} dm

Step-by-step explanation:

A square's diagonal cuts across the square, making two right triangles where the diagonal is the hypotenuse.

We have a right triangle with a hypotenuse of 29, and two legs that are the same length (because they are sides of a square)

So, we can use pythagoreans theorem to find the lengths of the legs, or sides of the square.

a^2 + a^2 = 29^2

2a^2 = 841

a^2 = 420.5\\

a = \sqrt{420.5}

Now that we have a side length of \sqrt{420.5}, we just have to multiply that by 4, since a square has 4 sides. This leaves us with a final perimeter of:

4\sqrt{420.5}

The circumference of a circle is 19 pi meters. What is the radius in meters?
Sliva [168]

Answer:

<h3>Area of a circle in terms of radius:</h3>

Area = π·r^2 = 3.14·9.5^2 = 283.5 square meters(*)

Area of a circle in terms of diameter:

Area = π·(d/2)^2 = 3.14·(19/2)^2 = 3.14·(9.5)^2 = 283.5 square meters(*)

Area of a circle in terms of circumference:

Area = C^2/4π = 59.69^2/4π = 3562.9/(4·3.14) = 3562.9/12.56 = 283.5 square meters(*)

(*) 283.52873698648 meters, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Step-by-step explanation:
