Answer:
282.7
Step-by-step explanation:
surface area of cylinder = 2πR² + 2πRh
R = 3 cm
h = 12 cm
surface area of cylinder = 2π*3² + 2π*3*12 = 90π ≈ 90*3.14 ≈ 282.7 (cm²)
Answer:
no then its not a right triangle
Step-by-step explanation:
X-30+x-30+x=180
3x-60=180
3x=240
X=80
Here, 1/7 = 3/4x + 1
3/4x = 1/7 - 1
3/4x = -6/7
x = -6/7 * 4/3
x = -2/7 * 4
x = -8/7
In short, Your Answer would be -8/7
Hope this helps!
