4. Ex. 1 – Find the Surface Area

5. What are the steps? A C B Draw Net Label Faces Label the lengths
7 in
14 in C
Draw Net
Label Faces
Label the lengths
What about the length of the rectangle? B
7 in

6. Remember… Length of the rectangle is also equal to the length around the circle (Circumference)
7 in
14 in C
7 in B

7. Remember.. To find Circumference..
C =  πd or C = 2πr
In our case, we have the radius, so we will use:
C = 2πr
C = 2(3.14)(7 in)
C = in

8. Now label the length A
7 in
L = in
14 in C
7 in B

9. 4. Find all the areas A
7 in
L = in
14 in C
7 in B

10. Find Areas A B C L = 43.96 in 7 in 7 in W = 14 in Area A A = π x r 2
A = (3.14)(7 in)2
A = (3.14)(7 in)(7 in)
A = in2
Area B
A = π x  r 2 
A = (3.14)(7 in)2
A = (3.14)(7 in)(7 in)
A = in2
Area C
A = L x W
A = (43.96 in)(14 in)
A = in2
Total Surface Area = in in in2
= in2
