Answer:

512

Step-by-step explanation:

Let the number of 7th graders in the school is x.

As three-quarters of them play at least one sport, so, the number of 7th graders who play sport = $\frac 3 4 x$ .

Among the 7th graders who play sports, half of them play more than one sport. So, the number of 7th graders who play more than one sport $= \frac 1 2\times \frac 3 4 x=\frac 3 8 x$ .

Among the 7th graders who play more than one sport, one-third of them play more than two sports. So, the number of 7th graders who play more than two sport $= \frac 1 3\times \frac 3 8 x=\frac 1 8 x$ .

Among the 7th graders who play more than two sports, one-quarter of them play more than three sports.

So, the number of 7th graders who play more than three sport $= \frac 1 4\times \frac 1 8 x=\frac{1}{32} x$ .

7th graders play more than three sports at the school= 16

$\Rightarrow \frac{1}{32} x=16$

$\Rightarrow x =16 \times 32$

$\Rightarrow x = 512$

Hence, the total numbers of 7th graders in the school are 512.

44 square feet

Diameter (4) divided by 2 is radius (2).

SA = 2πr^2 + 2πrh

SA = 2 * 3.14 * 2^2 + 2 * 3.14 * 2 * 3

SA = 2 * 3.14 * 4 + 2 * 3.14 * 2 * 3

SA = 6.28 * 4 + 6.28 * 3

SA = 25.12 + 18.84

SA = 43.96

Round to the nearest tenth.

SA = 44 square feet
