Complete table of values with working out

1 answer:

3 0

Assume an x-value, substitute it in the equation where you find "x" and solve to find y

x = 0
y = -18

x = 1
y = -14

x = 2
y = -8

x = 3
y = 0

x = 4
y = 10

Find the surface area of a cylinder with a height of 7 m and a base radius of 6 m.

weqwewe [10]

Answer:

489.84 m²

Step-by-step explanation:

Area of one 2d circle: πr² ⇒ π6² ⇒ 36π ≈ 113.04 (using 3.14 for pi)

Area of both 2d circles: 113.04 + 113.04 =226.08 m²

Now we have to find the width of the rectangle, which is equal to the circumference of either circle:

Width of rectangle: 2πr ⇒ 2π6 = 12π ≈ 37.68 (using 3.14 for pi)

We can find the area of the rectangle now, since the length was given

Area of rectangle: 37.68· 7= 263.76 m²

Surface Area: 263.76+226.08= 489.84m²

Hopefully this helps!
