10 pancakes produces 8 inches in diameter.
The area of 1 pancake is
Area = pi * r^2
Area = pi * 4^2
Area = 50.27 in^2
Then multiply it by 10
Total area = 502.65 in^2

A smaller pancake
Area = pi * r^2
Area = pi * 2^2
<span>Area = 12.56 in^2

Divide 502.65 by 12.56
= 502.65 / 12.65
= 39.74

So there are 39 pancakes.

telo118 [61]

Answer:

A 0.2 L water was filled into the bottle from faucet each seconds.

Step-by-step explanation:

Unit rate is defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

Given the statement: A 2 liter bottle is filled completely with water from a faucet in 10 seconds.

⇒ In 10 sec a 2L bottle is completely filled with water from a faucet.

Unit rate per second = $\frac{2}{10} = \frac{1}{5} = 0.2 L$
