Answer:
300 more times
Step-by-step explanation:
It is mentioned that a 12 years old blinks 150 times in 15 mins.
We know that 15 times 4 is 60 which results in 600 times in 60 minutes.
Again, an adult blinks 450 times in 30 minutes.
We know that 450 times 2 is 900
Next, subtract 600 from 900
equals to 300 times more
Answer:
33.14 ft^2
Step-by-step explanation:
First find the area of the circle
The diameter is 20 ft so the radius is 1/2 of the diameter of 20*1/2 = 10 ft
A = pi r^2 = pi ( 10)^2 = 100 pi
The central angle is 38
That is a fraction of the circle, which is 360 degrees
38/360 = 19/180
Multiply the fraction of the circle by the area
19/180 * 100 pi
19/9 * 5 pi
Using 3.14 for pi
33.144444
To the nearest hundredth
33.14 ft^2
