Ответ:
Sector area
Area of whole = 51.313
Area of unshaded = 9.424
Area of shaded = 41.8886
Ответ:
Step-by-step explanation:
Find the area of the bigger circle:
A = πr² = π(4 + 3)² = 49πFind the area of 120° sector AOC:
A = 120°/360°*A = 1/3*49π = 49π/3Find the area of smaller circle:
A = π(3²) = 9πFind the area of 120° sector of DOB:
A = 120°/360°*9π = 3πNow find the shaded area, the difference of areas of sectors:
49π/3 - 3π = 40π/3Ответ:
Dr Cash 1,166,400
Cr Notes Receivable 1,000,000
Cr Interest Revenue 166,400
Explanation:
To determine the net amount of the notes receivable that will be recorded, we must determine the present value of the note:
present value = 1,166,400 / (1 + 8%)² = 1,166,400 / 1.1664 = 1,000,000
