What is the area of the circle?

Mathematics
1 answer:
dmitriy555 [2]3 years ago
8 0

We know that the area of a circle has the formula A=πr²

We are given the diameter, and as we know that the diameter is twice the radius, we can divide the given diameter by 2.

27 ÷ 2= 13.5

Now, plug-in the number into the formula.

A=πr²

A=π×13.5²

A=π×182.25

(Assume π=3.14)

A=3.14 × 182.25

A=572.265

A=572.3 square meters.

Therefore, the area of the circle is 572.3 square meters.

The product of 2 √3 and 3 √12 simplified form is...
Serjik [45]
<h2>Greetings!</h2><h3>When multiplying two roots together, you can rearrange the equation so that the roots are next to each other and so are the whole numbers:</h3>

2 x 3 x \sqrt{3} x \sqrt{12}

<h3>This means that 2 x 3 is simple, = 6,</h3><h3>But when multiplying \sqrt{3} x \sqrt{12} you simply multply the two numbers and put them in a square root:</h3>

\sqrt{3} x \sqrt{12} = \sqrt{36}

<h3>But this can be square rooted to 6, which then means that the equation is now:</h3>

2 x 3 x 6 = 36

<h3>So the simplified form is 36.</h3>

Raju covers a certain distance in 1 hour and sham covers the same distance in 2 hours , who travels in a higher speed?
dimulka [17.4K]

Answer: Raju travels at a higher speed.

Step-by-step explanation:

Speed =\dfrac{Distance}{Time}

Speed inversely proportional to time.

As time taken to cover a particular distance decreases the speed will increase.

Raju covers a certain distance in 1 hour.

Sham covers the same distance in 2 hours.

1< 2

Thus Raju travels at a higher speed.
