I had some trouble with my astronomy work. I have to solve for a^3. The amounts given are below. The equation is: (M1 + M2) P^2 = 4pi/G(a^3)
M1 = 3.7 Msun star
M2 = 0.8 Msun star
P² = 7.7841 days
4(π)= 12.56
G = 6.67408 × 10^-11 m^3 kg^-1 s^-2
a³ = ?

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
