The lateral area of a cone is expressed as:

Lateral surface area of a cone: L = rs = √(r^2 + h^2)

L = п(9)√(9^2 +

L = 1159.248

40^2)

Therefore, the correct answer is the last option. Hope this answers the question. Have a nice day.

<h3>Hey there! </h3><h3>The word/ phrase "standard deviation" <u>means the measure of how to spread  out the numbers are </u></h3><h3>So, </h3><h3>52,61,31, 44, 47, 45, 25, 48, 47 standard deviation is/are most likely: \boxed{10.701765171119}  ← \boxed{answer}</h3><h3>In order for you to find out the standard deviation of this particular problem (or  problems of standard deviation) you had <u>to work out for the mean,</u> meaning to simplify the averages of each and every number, then  you would have  to<u> subtract your mean and your square for the outcome </u> Nextly, <u>workout your mean for those squared for your differences..</u> Lastly <u>take whatever your square of that number and keep it as your result/ outcome </u></h3><h3>Good luck on your assignment and enjoy your day! </h3><h3>~LoveYourselfFirst:)</h3>

9 cm and the other leg measures 11 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
nasty-shy [4]

Answer:

14.2 cm

Step-by-step explanation:

The hypotenuse of a triangle is measured using the pythagorean theorem. This formula sums up the squares of both legs of the triangle which would give the squared value of the hypotenuse. Therefore, we can then square root that value to find the hypotenuse. This would be the following...

9^{2} + 11^{2} = x^{2}

81 + 121 = x^{2}

202 = x^{2}

14.21 = x^{2}

Finally, we can see that the value of the hypotenuse is 14.2 cm
