If the diameter is 12 inches, the radius is 6 inches, because the radius is half the diameter.

Given the formula

A=\pi r^2

we have

A=36\pi

When you fold the circle in half, the resulting figure has half the area.

So, you start with a circle with area 36\pi

You fold it once and you have a semicircle with area 18\pi

You fold it twice and you have a quarter circle with area 9\pi

The perimeter of a rectangle is (10x2).if it's width is (2x-1),which expression represents the length
alexandr402 [8]

Answer: b. 3x + 2

Step-by-step explanation:

2l + 2w = p

2l + 2(2x - 1) = 10x + 2

2l + 4x - 2 = 10x + 2

2l = 6x + 4

l = 3x + 2

Find the length of the hypotenuse of a right triangle whose legs measure 6 and 5
Pavel [41]
A right triangle is a type of triangle which contains a right triangle. To be a right triangle, it should satisfy the Pythagorean Theorem which relates the three sides of the triangle. In this triangle, the longest side is called as the hypotenuse. To determine the hypotenuse, we use the Pythagorean Theorem which is expressed as follows:

c^2 = a^2 + b^2

where c is the hypotenuse

We calculate as follows:

c^2 = a^2 + b^2
c^2 = 6^2 + 5^2
c^2 = 61
c = √61

Therefore, the hypotenuse of the right triangle with sides 6 and 5 would be √61 which, clearly, is longer than the two sides.
