Answer:
Density is equal to mass/volume, so in your case:
density=1.3/1000=0.0013 g/cm^3
Step-by-step explanation:
Answer:
±sqrt( H *f•c)= L
Step-by-step explanation:
H=L^2/f•c
Multiply each side by fc
H *fc=L^2/f•c * fc
H *f•c=L^2
Take the square root of each side
±sqrt( H *f•c)= sqrt(L^2)
±sqrt( H *f•c)= L
Answer:
16 × π in 2
Step-by-step explanation:
the formula to find the area of a triangle is πr^2, you are given the diameter which equals 2r. so split the diameter in half and plug your number in. π4^2
4^2=16
16xπ
