Answer:
Step-by-step explanation:
Cylinder
Formula
V = pi * r^2 * h
r = 2
h = 5
pi = 3.14
V = 3.14 * 2^2 * 5
V = 62.8 cm^3
Cone
V = 1/3 * pi * r^2 * h
Same answer as the cylinder only take 1/3 of it.
V = 1/3 * 62.8
V = 20.933
Answer:
3
Step-by-step explanation:
12x+5(1)=41
12x=-5+41
12x=36
x=36/12
x=3
12(3)+5(1)=
36+5=41
Answer:
C. Yes, the density equals that of pure silver (10.5)
Step-by-step explanation:
Formula for the circumference of a circle:
C = πd or C = 2πr
[C = circumference π(pi) d = diameter r = radius(half the diameter)]
You know:
d = 5 feet
and you're using 3.14 for π, so substitute/plug it into the equation
C = πd
C = (3.14)(5)
C = 15.7 feet Your answer is B
The first 5 multiples of 3 are 3, 6, 9, 12, and 15.
