What is the perimeter of a square which has the same area as a circle with circumference of 4π?
Contact [7]
The circumference of a circle is given by: 2πr, where r is the radius of the circle. Equating 4π, we have 2πr = 4π so the radius of the circle is: r = 4/2 = 2. Then, the area of the circle is given by πr ^ 2 = π * (2 ^ 2) = 4π.Since the square and the circle have the same area, then: Let L be the side of the square, we have:  L ^ 2 = 4π, clearing L = 2 * (π ^ (1/2))The perimeter of a square is the sum of its sides:  P = L + L + L + L = 2 * (π ^ (1/2)) + 2 * (π ^ (1/2)) + 2 * (π ^ (1/2)) + 2 * (π) ^ (1/2))  P = 8 * (π ^ (1/2))

X-5y=2 and 9x+8=15 solve by substitution
lozanna [386]
x-5y=2
Hence x=2+5y   (Equation I)
9x+8=15             (Equation II)
Substituting Equation I in Equation II
9(2+5y)+8=15
18+45y+8=15
26+45y=15
45y=-11
Hence y= - \frac{11}{45}

Substituting this in Equation in I to get X

x-5(- \frac{11}{45} )=2
x+ \frac{11}{9}=2
x= 2- \frac{11}{9}
x= \frac{17}{9}

A right triangle with integer sides has area equal to 30. What is the length of its hypotenuse.
kozerog [31]

We have been given that a right triangle with integer sides has area equal to 30. We are asked to find the length of hypotenuse of right triangle.

We know that area of triangle is half the product of its base length and height.

Since our given triangle is a right triangle, so its base and height will be legs of right triangle.

\frac{1}{2}\cdot\text{Base}\times \text{Height}=\text{Area}

\frac{1}{2}\cdot\text{Base}\times \text{Height}=30

\frac{1}{2}\cdot 2\cdot\text{Base}\times \text{Height}=30\cdot 2

\text{Base}\times \text{Height}=60

This means that product of two bases is 60.

Now we need to find two multiples of 60 such that they are make a right triangle.

Multiples of 60:

1, 60

2, 30

3, 20

4, 15

5, 12

6, 10

We know that (5, 12 and 13) is a Pythagoras triplet.

5^2+12^2=13^2

25+144=169

169=169

Therefore, the hypotenuse of right triangle is 13 units.
