To find the surface area of a cylinder, add the areas of the two circles and the rectangular piece connecting them
area of circle: A = pi(r)^2
A = pi(7)^2
A = 49pi
area of rectangle: A = length X width
the length is the circumference of the circle
C = 2pi(r)
C = 2pi(7)
C = 14pi
multiply 14 pi by the width 5
area of rectangle: 70pi
add the areas of the two circles and the rectangle:
49pi + 49pi + 70pi = 168pi
ANSWER: 168pi
for the decimal if you use pi on the calculator then the answer is 527.8
but if u multiply by 3.14 the answer is 527.5
hope this helps!
Well, let's see. First we would need to find how much money he earns each DAY. To find THAT, we would need to multiply 760 times 1.5, which would be $1,140. Now, in order to find out how many DAYS it will take to make $3,420, you would divide 3,420 divided by 1,140, which will be 3. So it will take 3 days to earn $3,420.
I hope I helped! =D
Answer:
x = √(28), or x = 5.292
Step-by-step explanation:
First you distribute the square to the values inside of the parentheses. so it ends up looking like this
5(x^2 - 25) - 9 = 6
add 9 to both sides
so its 5(x^2 - 25) = 15
Then distribute the multiplication of 5 to the contents within the parentheses
so it would be 5x^2 - 125 = 15
add 125 to both sides
you get 5x^2 = 140
divide by 5 on both sides
you get x^2=28
then, take the square root of both sides to reverse the square
√(x^2)=√(28)
and in the end you get x=5.292
but √(28) will probably be fine if your teacher doesn't want u to solve for that kind of stuff.
120 people
40% of 200 is 80
200-80=120
so 120 people voted against the basketball court
Answer:
x≥-4
Step-by-step explanation:
-8x≤36-4
-8x≤32
x≥32/-8 when divide by minus you flip from≤ to ≥
x≥-4
