Illustrates whather the two ratios are equal or not using cross 3/27, 1/9​
vitfil [10]

Answer:

They are equal

Step-by-step explanation:

Given

\frac{3}{27}\ and\ \frac{1}{9}

Required

Determine if they are equal

We start by equating both:

\frac{3}{27} = \frac{1}{9}

Cross Multiply

3 * 9 = 1 * 27

27 = 27

Find the circumference and area of a circle with diameter 12 ft. Express your answer in terms of pie
xz_007 [3.2K]

Answer:

Circumference: 12π

Area: 36π

Step-by-step explanation:

The equation for the circumference of a circle is:

C = πd

Where C is the circumference and d is the diameter. Knowing this, we will be able to find the circumference by pugging in 12 for d.

C = 12π

And now we have found the circumference of the circle.

The equation for the area of a circle is:

A = πr²

Where A is the area and r is the radius. Remember that the diameter is double the radius, so we can find the radius:

12 = 2r

r = 6

Now that we know r, we can find the area of the circle:

A = π(6)²

A = 36π

Now we have found the area.

So the circumference is 12π and the area is 36π.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:
The shape has rotational symmetry.
The angle of rotation, taking color into account, is 360°.
