Macroeconomics calculation

find government spending with the follow information:
gdp = $123 million
consumer spending = $72 million
financial investment spending = $12 million
investment spending = $25 million
net exports = $5 million

so i know the formula is:
c + ig + g + (x - m) = gdp
i believe im finding g
i think it goes something like this:
72,000,000 + 25,000,000 + g + (5,000,000)
im not sure though and i need some more with the rest.
i have a few more questions like this so if anyone can explain this one too me, i can do the rest on my own

So if the equation you showed is a given, then you are on the right track. I'm trying to figure out where financial investment spending is in the equation, though?
I found this: The following equation is used to calculate the GDP: GDP = C + I + G + (X – M) or GDP = private consumption + gross investment + government investment + government spending + (exports – imports). ... It transforms the money-value measure, nominal GDP, into an index for quantity of total output.

72,000,000+12,000,000+25,000,000+ G + 5,000,000 = 123,000,000
It's easier to solve it without the zeros:
G=123 - 72- 12 - 25 - 5
G= 9 or 9,000,000 is government spending

Remember that (X-M) is NET EXPORTS. They will either give you exports and imports so that you have to subtract, or net exports that you can just plug in. Make sense?

Answer: 10pi

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

Whose mistake? can you give more details to what the question is asking?
