<u>First, create M</u> (the set of all perfect square roots less than 100)

1² = 1, 2² = 4, 3² = 9, 4² = 16, 5² = 25, 6² = 36, 7² = 49, 8² = 64, 9² = 81, 10² = 100 (disregard 10² since it is not LESS THAN 100)

M = {1, 2, 3, 4, 5, 6, 7, 8, 9}  <em>not sure if you want to include the negatives)</em>

<u>Next, create N</u> (the set of all even number less than 30)

N = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28}

<u>M ∩ N</u> = {2, 4, 6, 8}

Please help I’ll mark you as brainliest if correct
Alecsey [184]

Answer:

153.94 is your answer.

Step-by-step explanation:

I believe it would be the last one, but let me explain. So to find the area of a circle with just the diameter, the formula would be 1 /4 π d2. Which is one fourth times pie, multiplied with the diameter to the second power. So if we put 14 in the equation would look like this 1/4*π*14*2. So if we use this formula, we get 153.94. Or something close to that. I hope this helps! Good luck!! ;)

I need help asap with this
tatyana61 [14]

Answer:

51°

Step-by-step explanation:

Given

<QPR = 39°

<PQR = 90° ( inscribed angle in semi circle)

Now

<QPR + <PQR + <PRQ = 180° { being sum of angles of triangle)

39° + 90° + <PRQ = 180°

<PRQ = 180° - 39° - 90°

<PRQ = 51°

Hope it will help :)
