Answer:
21.98in²
Step-by-step explanation:
The section of the birthday pie that Karen ate forms a sector.
The central angle of this sector is 70°
The diameter is 12 inches.
This means the radius which is half of the diameter is 6 inches.
The area of the section that is leftover is given by:
We substitute to get:
Let Rs.x and Rs.y be the cost of a knife and a spoon respectively.
From question,
x = 2y --- (1)
and,
12x + 8y = 46.08
=> 12×2y + 8y = 46.08
=> 24y + 8y = 46.08
=> 32y = 46.08
=> y = 46.08/32
=> y = 1.44
putting y = 1.44 in (1)
=> x = 2×1.44
=> x = 2.88
Therefore, cost of a knife is Rs 2.88
Add them up and divide by 180
