Answer:
1733.28
Step-by-step explanation:
we want to find the surface area of the cylinder
We are given:
diameter = 12in
height = 40in
formula to find surface area of a cylinder: SA = 2πr^2 + 2πrh (where h = height and r = radius)
in order to find the SA of a cylinder we need to know the radius
we are given that the diameter is 12
we can acquire the measure of the radius by dividing the diameter by 2 ( this is because the radius is equal to half of the diameter )
so r = 12/2 = 6
now to find the surface area,
we simply plug in the values of the radius and height into the SA of a cylinder formula
SA = 2πr^2 + 2πrh
r = 6
h = 40
( note it says use 3.14 for π )
substitute values
SA = 2(3.14)(6)^2 + 2(3.14)(6)(40)
if you plug this into a calculator you get that the surface area is 1,733.28
Undefined. That equation is the y axis and therefore intercepts the y axis at every point
Answer:There are 1180 mm in 1m and 18cm
Step-by-step explanation:
There is 1000mm in 1 m and 180mm in 18cm add them up and you get 1180
36 for 4 hats = 36/4 = 9 per hat
56 for 7 hats = 56/7 = 8 per hat
not equivalent
12 posters for 36 students = 12/36 = 1/3 poster per student
21 posters for 63 students = 21/63 = 1/3 poster per student
these are equivalent...although it does not make much sense...each person getting 1/3 of a poster. And if there was a mistake and it was supposed to be 36 posters for 12 students and 63 posters for 21 students...it would still be equivalent
