Answer:
(a) 10.0 m²
Step-by-step explanation:
The radius of the inner circle is (2 m -1.1 m) = 0.9 m. The area of each circle is given by the formula ...
A = πr²
so, the difference in areas is ...
shaded = π(2 m)² -π(0.9 m)² = π(4 -0.81) m²
shaded area ≈ 10.0 m²
Answer:
i don't know sorry :(
Step-by-step explanation:
Answer:
Width = 3x So,
Length = x 3w + w = 56/2 = 28
3x + x = 4x
56 / 4 = 14 w = 7
x = 14
14 x 3 = 42
