Answer:
A = pi*(8 mm)^2 = 64*pi mm^2
Step-by-step explanation:
The formula for the area of a circle is A = pi*r^2, where r is the radius. Thus, r^2 = (25pi) / pi, or 25, and r = 5 mm.
If we increase this radius by 3 mm, we get the new radius 8 mm. The area of the new circle will thus be A = pi*r^2, or, in this particular case,
A = pi*(8 mm)^2 = 64*pi mm^2.
So men to women=3 to 4
210 men
210 represents 3 units
wome=4
210=3 units
divide by 3
70=1 unit
multiply by 4 to find women
280=women
total workers=women+men
women=280
men=210
280+210=490
total =490
Answer:
log (448)
Step-by-step explanation:
3 log(4) + log(7)
We know that a log b = log b^a
3 log(4) + log(7)
log 4^3 + log 7
log 64 + log 7
We know that log a + log b = log (a*b)
log (64 *7)
log (448)
