Answer:
Step-by-step explanation:
First both the rational numbers should have same denominators. So, find least common denominator
Least common denominator is 10

Now multiply the numerator and denominators of the both the numbers by 10.

6: -8+4V
8: -9-15V OR -9+(-)15V
10:-17+33V
For this case, the surface area of the cylinder is given by:
A = 2 * pi * r * h + 2 * pi * r ^ 2
Where.
r: cylinder radius
h: cylinder height
Substituting values we have:
A = 2 * 3.14 * 5 * (2 * 5) + 2 * 3.14 * 5 ^ 2
A = 471
Answer:
The total surface area of the cylinder is:
A = 471
Answer:
casey's age is 7
Step-by-step explanation:
if his sister is 3 times as old as he is then she is older therefore you would devide.
21/3=7
Answer:
3x +45°=180° (due to straight angle)
or, 3x= 180°-45°
or,3x= 135°
or,X=135°/3
X =45°.ans
