Calculate the circumference of the circle, and multiply it by 23.
C = pi * d
C = 3.14 * 63 ft =197.82 ft
23 * C = 23 * 197.82 ft = 4549.86 ft

Answer:
No, she doesn't have enough varnish for all the floors.
Step-by-step explanation:
Area of the floor, A= 10x6-5x2=50 
Since 5 m^2 required 1 liter of varnish.
So, the amount of varnish required for 1 = 1/5= 0.2 liters.
The amount of varnish required for 50 = 0.2X50=10 liters.
Now, as 1 tin has 2.5 liters of varnish.
So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.
Hence, she doesn't have enough varnish for all the floors.
The lateral area of a cone is 147ft².
The total surface area of the cylinder is 867ft².
The total surface area is 1014ft²
<h3>What is the lateral surface area of a cone?</h3>
The lateral area of a cone is defined as the area covered by the curved surface of the cone.
Lateral area of a cone = πr x √(r² + h²)
Where:
- r = radius = 12/2 = 6ft
- h = height = 5ft
- π = 3.14
3.14 x 6 x √(36 + 25) = 147ft²
<h3>What is the total surface area of the figure ?</h3>
Total surface area of the cylinder : πr(r + 2h),
(3.14 x 6) x (6 + 40) = 867ft²
Total surface area = 867 + 147= 1014ft²

Answer:
Zero
Step-by-step explanation:
Failure Rate = 1 in every 5 hours
It is important to consider the time that it takes for 2 components to fail
* Standard deviation is not given for failure rate hence it is assumed to be zero.
What is the probability that 12 hours will elapse before 2 components fail?
In other words, what is the probability that it takes 12 hours for 2 components to fail?
This probability is = 0
This is because the time it takes for 2 components to fail is 10 hours.
No adjustment can be made for this time, as there is no stipulated standard deviation.
