Answer:
dv= 989100cm^3
Explanation:
The volume of a sphere can be calculated using below formula
Volume of a sphere = 4/3 π r^3
Therefore, for a hemisphere, V= 2/3 pi r^3
V=(4/3)πr³
V= 2/3πr³
dV/dr=4πr²
Then we need to pproximate dV/dr with
ΔV/Δr then we have
Volume of hemispherical some is one half of the the volume of a sphere where dr is change in radius, dv is change in volume
dV/dr=2πr²
Take the derivative of V with respect to r then we have
dV=2πr²dr
where
Radius = diameter/2
Our diameter is 30cm then
r=30m/2 = 15cm
Then we convert to cm we have
r= 1500cm
dv= 2×π ×(1500)^2 × 0.07
dv= 989100cm^3
the amount of paint in cubic centimeters needed to apply a coat of paint 0.07 cm thick to a hemispherical dome with a diameter of 30 meters is
989100cm^3

The answer is "<span>Google Recaptcha".

CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart and Google's reCAPTCHA is the main CAPTCHA service on the Web. You've likely observed CAPTCHAs a million times on join pages over the Web; to isolate people from spam bots, a test will fly up soliciting you to unravel a photo from words or numbers, choose questions in a lattice of pictures, or simply click a checkbox. Presently, however, you will see CAPTCHAs less and less, not on account of Google is disposing of them but rather in light of the fact that Google is making them undetectable.
The real exchange rate is 1 dollar = 2 Argentine pesos
The exchange rate is an economic term to refer to the relationship between two currencies. The exchange rate establishes the proportion of value that exists between two currencies. For example:
- 1 Dollar is equivalent to 4 Argentine pesos
However, this rate does not represent reality in some places, there may be situations in which the proportions established by the exchange rate are not faithful to reality. For example:
- 3 Dollars or 6 Argentine pesos are used to buy 1 gallon of milk.
In this example, it is evident that in reality, the dollar is not equivalent to 4 Argentine pesos but to 2 due to the proportion of value concerning a product. Therefore, the real exchange rate is 2 Argentine pesos for every American dollar.

Answer:
The variance is: $ 0.50 per direct labor hour.
Explanation:
Actual payroll = $117,000/6000h = $19.50 per hour
So, if we compare this value with the standard rate of pay ($20 per direct labor hour) The variance is: $20.00 - $ 19.50 = $0.50 per hour
