Answer: Surface Area = 16in.

Step-by-step explanation:

So we need to find the area of each side and add them up.

First we find the area of one of the triangular sides: 2*3/2 = 3

Then we multiply it by 4 to accommodate the 4 sides that are the same size: 12

Then we do 2*2 = 4 for the base. We then add those up.

4 + 12 = 16

A bicycle training wheel has a radius of 3 inches. The bicycle wheel has a radius of 10 inches. Approximately how much smaller,

zhuklara [117]

Answer:

$285.74\text{ inch}^2$

Step-by-step explanation:

GIVEN: A bicycle training wheel has a radius of $3\text{ inch}$ . The bicycle wheel has a radius of $10\text{ inch}$ .

TO FIND: Approximately how much smaller, in square inches, is the area of the training wheel than the area of the regular wheel.

SOLUTION:

radius of bicycle wheel $=10\text{ inch}$

area of bicycle wheel $=\pi r^2$

putting value,

area of bicycle wheel $=3.14\times10^2$

$=314\text{ inch}^2$

radius of bicycle training wheel $=3\text{ inch}$

area of bicycle training wheel $=\pi r^2$

putting value,

area of bicycle wheel $=3.14\times3^2$

$=28.26\text{ inch}^2$

difference in area of bicycle wheel and bicycle training wheel

$=\text{area of bicycle wheel}-\text{area of bicycle training wheel}$

$=314-28.26$

$=285.74\text{ inch}^2$

hence the training wheel is $285.74\text{ inch}^2$ smaller than regular wheel

Over the last 40 years, the percent decrease in egg consumption in the U.S. is 35%. Forty years ago, the average consumption was

Kisachek [45]

Answer:

260 eggs per person per year.

Step-by-step explanation:

We have been given that over the last 40 years, the percent decrease in egg consumption in the U.S. is 35%. Forty years ago, the average consumption was 400 eggs per person per year.

To find the average consumption of eggs today, we will find 65% (100%-35%) of 400.

$\text{The average consumption of eggs today}=\frac{65}{100}\times 400$

$\text{The average consumption of eggs today}=65\times 4$

$\text{The average consumption of eggs today}=260$

Therefore, the average consumption of eggs today is 260 eggs per person per year.
