Answer:

26/40

Step-by-step explanation:

Since the question asks the person this, what is the probability a club member is NOT a 7th grader. This means we have to find the probability of not being a 7th grader. the probability of it being a 7th grader is 14/40. This mean I subtract 14 from 40 to get 26. You can also add the probabilities from the 6th graders and 8th grades to also get 26/40.

Edit: Now that I just saw the simplifying of the previous answer I just realized that I didn't simplify. 13/20 is simplified. Props to the previous answer for doing what I did not.

Find the volume of a cylinder with radius 5.7cm and height 10 cm, correct to 1 decimal place

Veseljchak [2.6K]

$\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=5.7\\ h=10 \end{cases}\implies \begin{array}{llll} V=\pi (5.7)^2(10)\implies V=324.9\pi \\\\\\ V\approx 1020.7 \end{array}$
