Answer:
133 windows
Step-by-step explanation:
It is given that,
A window washer cleaned 38 windows in 2 hours.
We need to find how many windows did he clean in 7 hours.
2 hours = 38 windows
1 hour = 19 windows
For 7 hours, multiply 19 and 7.
7 hours = 19 × 7 windows
= 133 windows
Hence, in 7 hours he can clean 133 window
is the disk of radius 1 parallel to the

(the orientation doesn't matter because this is a scalar surface integral)

Do you have trouble comparing the values in one table to those in the other?
f(x) = 3 for all values of x, so you only need to find the entry in the g(x) table where g(x) = 3. The corresponding x-value is
.. x = -1
The answer is 452.16 cm³.
Formula to calculate the volume of cone = V = πr²x h/3
Now r = 6 cm and h = 12cm, and value of π = 3.14
By putting the values,
V = (3.14) (6)² (12/3) = (3.14)(36)(4)
V = 452.16 cm³

The answer is 1.705 in decimals
