Answer:
- CSA of the cylinder = 440 sq. cm
- Volume of the cylinder = 1540 cu. cm
Step-by-step explanation:
Given:
- Radius of the cylinder = 7 cm
- Height of the cylinder = 10 cm
To Find:
- Curved surface area
- Volume
Solution:
Using formula:
<em>Substituting the required values: </em>
Now,
<em>Substituting the required values, </em>
Hence,
- CSA of the cylinder = 440 sq. cm
- Volume of the cylinder = 1540 cu. cm
Answer:
Step-by-step explanation:
The perpendicular is equal to 6. That's because the left triangle's missing angle is 180 - 45 -90 = 45
The angle in the right triangle is given as 52.
The cos(52) = adjacent side (which we just found to be 6) / y
Multiply both sides by y
y cos(52) = 6
cos(52) = 0.6157
Divide by sides by cos(52)
y = 6 / cos(52)
y = 6 / 0.6157
y = 9.76
2y + 2x = 6
2y - x = 12
Subtract
3x = -6, x = -2
2(-2) + 2y = 6
-4 + 2y = 6
2y = 10, y = 5
Final solution: x = -2, y = 5
The answer is C 52 degrees
