The circumference of a circular stage is 157 feet. If Chris paints the stage at a rate of 400 square feet per hour, how long would it take to the nearest hour, for Chris to paint the entire stage?
Answers
c = 2*pi*r
a = pi*r^2
lets find the radius from the first equation:
r = c/2*pi
r = 157/(2*3.14)
r = 24.99 ft
now lets calculate the area:
a = pi*r^2
a = 3.14*(24.99)^2
a = 1960.93 ft^2
Now we need to divide the total area by the rate at which Chris paints, and that gives us the time needed:
time = 1960.93/400
time = 4.9 hours
that would be 5 hours rounded to the nearest hour

The correct statement will be that the there are 135 even numbers ranging from 30 to 300 inclusive of the numbers. The digit "6" will be repeated for a number of 63 times.
The calculation of repeated digit "6" can be done by applying simple calculations or even can be calculated on the fingers.
- Even numbers are referred to as those numbers whose last digit ends with either 0,2,4,6 or 8. There are a total of 270 digits between and half of them will be even. So even digits are 135 inclusive of both the numbers.
- The calculation where 6 is repeated is done by applying the information that there will be 17 times 6 appears between values 30 to 99.
- Between 100 to 200 and 201 to 300, "6" is repeated 23 times in each of the ranges.
- Calculation of "6" is as below,
- So we now know that there are 135 digits that are even and 63 times the digit 6 is repeated in the range 30 thru 300.
Hence, the correct statement is that there are 135 even digits between the range of 30 to 300 and digit 6 is repeated for a number of 63 times.

Step-by-step explanation:
In the Numbers from 30 to 99 the 6 will be written 1*4 + 6*1 + 1*1*2 = 12
In the Numbers from 100 to 300 the 6 will be written 0 + 3*1*4 + 3*9*1 + 3*1*1*2 = 45
So the six will be written 12 + 45 = 57 times
