Answer:
$38.50
Step-by-step explanation:
We are told the cost of the fabric per meter, so we first need to convert 250 cm into meters.
1 meter = 100 cm
Therefore, 250 cm = 250 ÷ 100 = 2.5 meters
cost of fabric = $15.40 per meter
To calculate the total cost, mulitply the length in meters by 15.40:
2.5 x 15.40 = 38.50

To find the total surface area of the cylinder
We get
S.A=2πr^2+2πrh
S.A=2×3.142×4×4+2×3.142×4×10
S. A=100.544inches sq+251.36inches sq
S. A=351.904inches sq
Answer:
