Answer:
1507m²
Step-by-step explanation:
Given parameters:
Radius of cylinder = 12m
Height of cylinder = 8m
π = 3.14
Unknown:
Surface Area of cylinder = ?
Solution:
The surface area of any body is the sum of all the area that covers a body.
For a cylinder, the surface area is given as;
SA = 2πr² + 2πrh
Where SA = Surface Area
r = radius of cylinder
h = height of cylinder
Now input the parameters in the given equation and solve;
SA = (2 x 3.14 x 12²) + (2 x 3.14 x 12 x 8)
SA = 904.32 + 603.264
SA = 1507.584m² = 1507m²
Answer:
156
Step-by-step explanation:
Let number of juniors be j and number of seniors be s
Thus, we can write:
<u> 236 juniors and seniors in Mr. Jay's math class:</u>
j + s = 236
Also
<u>There are 4 fewer juniors than twice the number of seniors:</u>
j = 2s - 4
Now putting equation 2 into 1, we can solve for s:
j + s = 236
2s - 4 + s = 236
3s = 240
s = 80
Hence, juniors is:
j = 2s - 4
j = 2(80) - 4
j = 156
There are 156 juniors
