Answer:
The area of remaining sheet is 1077cm²
Step-by-step explanation:
First, you have to find the area of circle using the formula, A = πr², where r is the radius of circle:
r = 20cm
A = π × 20²
= 400π cm²
Second, you have to find the area of rectangle:
A = 12 × 15
= 180 cm²
Lastly, you need to substact the area of rectangle feom the area of circle to find the remaining sheet that has not being cut:
A = 400π - 180
= 1077 cm² (3s.f)

Answer:
$12.78.
Step-by-step explanation:
To determine the expected price of a good in 2000, knowing that in 2015 it cost $ 17.6 and that the consumer price indexes were worth 172.2 in 2000 and 237.017 in 2015, the following calculation must be performed:
237.037 = 17.6
172.2 = X
X = 172.2 x 17.6 / 237.037
X = 3,030.72 / 237.037
X = 12.78
Thus, the expected price of the good in the year 2000 is $ 12.78.
