On the way home from rug shopping, Sophia stopped and bought a rectangular cake. The bottom is not frosted, but all other sides
Brums [2.3K]

Answer:

A) Total Surface Area = 164 sq. feet.

B) Radius = 4.5 inches

C) Diameter = 9 inches

Step-by-step explanation:

A)

A rectangular prism has 6 faces. Since bottom is not covered in frosting, we only need to find area of all the 5 faces (surfaces) and sum it.

<em>The length is 8, width is 11, and height is 2 (of the cake).</em>

<em />

Hence, top surface is 8 * 11 = 88

There are 2 sides measuring 8 and 2. So area is 8*2= 16 *2 = 32

THere are other 2 sides measuring 11 and 2. So area is 11 * 2 = 22 * 2 = 44

Total surface area of the cake that has frosting = 88 + 32 + 44 = 164 sq. inches

B)

Top of the cylinder (pineapple cake) is covered in icing. Top is the shape of a circle, which has area  \pi r^2, which is given as 63.585

Solving for radius (r), we get:

\pi r^2=63.585\\r^2=\frac{63.585}{\pi}\\r=\sqrt{\frac{63.585}{\pi}}\\ r=4.5

radius = 4.5 inches

C)

The diameter is <em>twice the length of the radius</em>.

The diameter is thus D = 2 * r

D = 2 * 4.5 = 9

Diameter = 9 inches

Do the data in the table represent a direct variation or inverse variation? Write an equation to model the data in the table?
notsponge [240]

Based on the given data; the table represent an inverse variation and the equation that model the data in the table is y = 8/x

<h3>Variation</h3>

  • Direct variation

y = k × x

4 = k × 2

4 = 2k

k = 4/2

k = 2

when y = 2 and x = 4

y = k × x

= 2 × 4

y = 8

  • Indirect variation

y = k/x

4 = k / 2

8 = k

when y = 2 and x = 4

y = k/x

2 = k/4

2 × 4 = k

k = 8

So,

y = k/x

y = 8/x
