Answer:
Step-by-step explanation:
Given
c = hypotenuse
Required
Find c
Using Pythagoras theorem, we have:
Substitute values for a and b
Take square roots of both sides:
Express 20 as 4 * 5
Split surd
Take square root of 4
The total surface area of the soup can would be
equivalent to the sum of the surface area of the 2 covers plus the surface area
of the side.
Surface area of the 2 covers = 2 π r^2
Surface area of the 2 covers = 2 π (2.5 cm)^2
Surface area of the 2 covers = 39.27 cm^2
Surface area of the side = 2 π r h
Surface area of the side = 2 π
(2.5 cm) (9 cm)
Surface area of the side = 141.37 cm^2
Total surface area = 39.27 cm^2 + 141.37
cm^2
<span>Total surface area = 180.64 cm^2</span>
