Answer:
B. l = (S - πr^2) / πr
Step-by-step explanation:
S = πrl + πr^2 solve for l
πrl = S - πr^2
l = (S - πr^2) / πr
Answer is B. l = (S - πr^2) / πr
Solve for L (get L by itself)
S = πrl + πr² First subtract πr²
S - πr² = πrl Then divide πr to get L by itself
(S-πr²) ÷ (πr) = l Your answer is B
10: 12 units^2 11: 33 units^2
10:
Divide into square and 2 triangles (for simplicity)
square=9
one triangle=3/2
both triangles combined=3
9+3=12
11:
divide into 2 triangles
top triangle: height= 4, base=6
bottom triangle: height= 7, base=6
top=12
bottom=21
Add, 33.
