Answer: (D)
Explanation:
Just a note on writing down these expressions: I recommend using parentheses whenever you can to avoid misinterpretation. An expression 1/x-1/y / 1/x+1/y could be interpreted by someone as 1/x-(1/y / 1/x)+1/y, which is a different thing.
Answer:
<u>Each of the 4 sectors have an area:</u>
- πR²/8 - πr²/8, where
- R = 28/2 - 2 = 12 in
- r = 6/2 = 3 in
<u>Find the area:</u>
- A = π/8(12² - 3² ≈ 53 in²
<u>Outer perimeter of the frame:</u>
- P = d + πd/2 =28( 1 + π/2) ≈ 72 in
