Find Y .............. ​

Mathematics
1 answer:
N76 [4]4 years ago
4 0

Answer:

y = 40 / sqrt(pi)

Step-by-step explanation:

The area is 400

We want to find the diameter

400 = pi r^2

Divide each side by pi

400/ pi = r^2

Take the square root of each side

sqrt(400/ pi) = sqrt(r^2)

20/ sqrt(pi) = r

The diameter is twice the radius

2 r = d

2 * 20/ sqrt(pi) = d

40 / sqrt(pi) =d

y is the diameter so

y = 40 / sqrt(pi)

Which of the following best defines 2 2/3?
inna [77]

Answer:

A. \sqrt[3]{4} = Cube root of 4.

Step-by-step explanation:

We have been given an expression 2^{\frac{2}{3}}. We are asked to find the equivalent expression for our given expression.

Using exponent property \sqrt[n]{a^m} =a^{\frac{m}{n}, we will get,

2^{\frac{2}{3}}=\sqrt[3]{2^2}

2^{\frac{2}{3}}=\sqrt[3]{4}

Upon looking at our given choices, we can see that option A is the correct choice.

What is 3/8<br> as an equivalent fraction with the LCM as the denominator?
tino4ka555 [31]

Answer:

3/8 = 9/24

Step-by-step explanation:

So here we have a basic multiplication problem and finding the LCM of 8 and 3. The first step in this problem is finding the LCM of 3/8. The LCM of 3 and 8 is 24. So yay! we have the bottom half of our answer!

Ex.-

The LCM of 8 and 3 is 24.

So now we have to find an equivalent fraction. Since we already know that 8 (the denominator in the original equation) can be multiplied by 3 to equal 24, we use 3 (the numerator in the original equation) and multiply it by itself to get an equivalent fraction.

Ex.-

8 x 3 = 24

3 x 3 = 9

Now that we have our numerator and denominator, all we have to do now is put them together to get our answer.

Ex.-

9/24 (answer) = 3/8 (original equation)

Hopefully I could help! :)
