To find a volume of a cylinder we use the following formula:
Plug in the values:
Take the square:
Multiply the numbers:
Answer: 69
Step-by-step explanation: a triangle adds up to 180 degrees. It is an isosceles triangle (2 sides are the same angle) 180-42=138 then do 138/2=69
Answer:
y = 3x - 8
Step-by-step explanation:
Answer:
53/5
Step-by-step explanation:
since 10 is the denominator of the denominator we can move it to the numerator, giving us 10n/5-3n = 1/5
multiply all sides by 5-3n, giving us 10n = (5-3n)/5
now multiply by 5 to get rid of the final denomintor, 50n = 5-3n
move 3n to the other side 53n = 5, n = 53/5
8a^2 + 3a^2
11a^2
since both have a^2 you only have to add the coefficients
