Answer:
area = 138 m²
Step-by-step explanation:
radius of large circle = 12 m
radius of small circle = 10 m
large circle area = πr² = (3.14)(12²) = 452.16 m²
small circle area = πr² = (3.14)(10²) =314 m²
452.16 - 314 = 138.16 m²
Answer:
He missed 14 questions
Step-by-step explanation:
Total = Right + Miss ⇒ t = r + m
Right = Miss + 12 ⇒ r = m + 12
t = 40
Since t = r + m and r = m + 12 then:
t = m + 12 + m
t = 2m + 12
40 = 2m + 12
28 = 2m
m = 14
