➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2
To start with, we can use this:
2 (r^2)
^^ This represents the surface area of the two circles
A cylinder also has a rectangle which is rolled to form the shape
As we know, the formula of a rectangles area is length x width
The width of the rectangle would be equal to the circumference of a circle
circumference of circle =
The length of the rectangle would be the height of the cylinder
We can use this:
This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.

Answer:
103.2 km
Step-by-step explanation:
Hi there!
<u>1) Draw a diagram</u>
Please see the picture below.
<u>2) Solve for the length of the diagonal</u>
Because Jacob's path creates a right triangle, we can use the Pythagorean theorem: where c is the side opposite the right angle and a and b are the other sides
Plug in the known information
Take the square root of both sides to isolate c
I hope this helps!
Something that can be divided by 34 is 3
Since this is a 45-45-90 right triangle, we can use one of it's properties to easily find the hypotenuse.
In a right triangle like this, the hypotenuse always has a value that's √2 times larger than the legs (the other sides).
Thus, let's multiply 3√2 by √2.
(3√2)(√2)
= 3√4 = 3*2
= 6
That should be your answer. Happy studying~
