Answer:
360 cm^2.
Step-by-step explanation:
Area of the base = 10*10 = 100 cm^2.
We find the slant height of the sides using Pythagoras:
h = sqrt ( 12^2 + 5^2)
h = sqrt 169
h = 13.
Area of the triangular sides = 4 * 1/2 * 10* 13
= 260 cm^2
So the total surface area = 100 + 260
= 360 cm^2.
A) square
B)square based pyramid
Answer:
exponential function, cool
Step-by-step explanation:
looks like f(x) = e ^x
So f(3) would be e^(3)
you can work this out on your calculator.
press [2ndf] [e^x]] [3] = 20
Best thing is draw a line up from x-axis to the curve, where it hits the curve you will have your answer
Answer:
3183.96 ft^3
Step-by-step explanation:
let pi = 3.14
volume of a cylinder is base * height
find the base: (area of circle)
height is given
container A:
circle area = 530.66
multiply 530.66 by the height (13)
530.66 * 13 = 6898.58
container B:
circle area = 530.66
multiple 530.66 by the height (19)
530.66 * 19 = 10082.54
Find empty space:
10082.54-6898.58 = 3183.96
