Answer:
400 grams
Step-by-step explanation:
If the equation is density = mass / volume, fill it out to find mass
10 = x / 40
400 = x
x = 400 g
0.3×1.2
=0.36
−0.3,1.2→Negative
−0.36
A = 50.26 sq meters
we have to find the diameter first by using the circumference:
C = πd
25.12 = πd
25.12/π = d
8 = d
this means the radius is 4
A = πr²
A = π4² or 16π
y=65x
x represents the # of hours
