victus00 [196]

Answer:

75% of the votes were in favor.

Step-by-step explanation:

The question is "What percent(rate) of 56 is 42?"

So fill in the formula and it will show as r=42/56, which is the rate will be equal to 42 divided by 56.

Perform the calculations and the result will show 0.75

Convert the decimal to a percent by moving the decimal point two places to the right and you will have 75% as your answer.

When baking a cake, you have a choice of the following pans:
STALIN [3.7K]

Answer:

round cake - 82.42 in^2

rectangular cake - 114 in^2

Round cake:

d = 7 in

r= d/2 = 7 in /2 = 3.5 in

h = 2

The surface area of a cylinder is: A = 2pie r^2 + 2pie rh The surface are of the round cake (cylindrical cake) excluding the bottom is

Area = 2pie r^2 + 2pie rh - pie r^2

Area = pie r^2 + 2pie rh

Area = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2

= 38.46 + 43.96

= 82.42 in^2

Rectangular cake:

w = 6 in |= 9 in h = 2 in

The surface area of a rectangle

A = 2wl + 2wh + 2lh

The surface are of the rectangular cake excluding the bottom is

A = 2wl + 2wh + 2lh - wl

A = wl + 2wh + 2lh

A = 6 * 9 + 2* 6 * 2 +2 *9 * 2

= 54 + 24 +36

= 114 in^2
