Answer:
y = 57
Step-by-step explanation:
y α x
y = kx ; k = Constant of proportionality
81 = k* 54
k = 81/54
k = 1.5
Value of y when x = 38
y = kx
y = 1.5 * 38
y = 57
Hence, y = 57 when x = 38
Answer:
LK = 38
Step-by-step explanation:
MN is the midsegment, and the midsegment is the average length of the top and bottom, so:
solve for LK:

Answer:
16022 square foot
Step-by-step explanation:
The world's largest cookie was baked in North Carolina in 2003. Its diameter was 100 feet and it contained about 6,000 pounds of chocolate chips! If the cookie was a cylinder 1 foot tall, and you wanted to cover it with icing, how many square inches would you have to ice? Use 3.14 for .
We find the surface area of the cylinder
= 2πr(r + h)
r = Diameter /2 = 100 feet/2
r = 50 feet
h = 1 feet
Hence
2 × 3.14 × 50(50 + 1)
= 16022.122533 square foot
= 16022 square foot
