The bakery Delicias Culinarias sells wedding cakes that are shaped like cylinders with heights and diameters shown below

Art [367]

Answer:

The icing cover refers to the surface area of the cake.

Surface area of cylinder = 2*pi*r^2 + 2*pi*r*h

Surface area of cylinder without bottom area = pi*r^2 + 2*pi*r*h

Subtracting the areas, we have Difference = 254.5 in2

Step-by-step explanation:

The icing cover refers to the surface area of the cake.

The surface area of a cylinder is given by:

S = 2*pi*r^2 + 2*pi*r*h

As we don't need to cover the bottom of the cake, we can use the following formula:

S = pi*r^2 + 2*pi*r*h

So for the bigger cake, the radius is 7 inches and the height is 8 inches, then we have:

S1 = pi*7^2 + 2*pi*7*8 = 505.7964 in2

The smaller cake has a radius of 4 inches and height of 8 inches, so:

S2 = pi*4^2 + 2*pi*4*8 = 251.3274 in2

To find how much area will be covered more for the bigger cake, we just need to find the difference of the bigger cake area by the smaller cake area:

Difference = S1 - S2 = 505.7964 - 251.3274 = 254.469 in2

Rounding to nearest tenth, we have Difference = 254.5 in2

Answer:

y=8x or y=8x + 0

Step-by-step explanation:

you need to take 2 points on the lina and make a triangle i used (-2,16) and (0,0).

The equation for gradient is

$\frac{rise}{run} = \frac{16}{2} = 8$

and the line touches the Y-axis at 0(that is your y-intercept)
