Answer:
2 g/cm³
Step-by-step explanation:
The volume is not given, so find that first:
2 cm x 3 cm x 2 cm = 12 cubic cm = <em>V</em>
Mass is given: <em>m </em>= 24 g
Using the density formula, solve:
<em>d </em>= <em>m</em>/<em>V</em>
<em>d </em>= 24 g/12 cubic cm
<em>d </em>= 2 g/cubic cm

Answers:
Area = 254.34 square feet
Circumference = 56.52 feet
=========================================================
Work Shown:
Area = pi*(radius)^2
A = pi*r^2
A = 3.14*9^2
A = 254.34 square feet
----------------
Circumference = 2*pi*(radius)
C = 2*pi*r
C = 2*3.14*9
C = 56.52 feet
The two results are approximate since pi = 3.14 is approximate.
Answer:
Step-by-step explanation:
R means Rosa
given:
R+b+c=36
R R c-2=b, (R+2)+2=c
b-2=R, R+2=b
.
R+b+c=36 substitute for b and c
R+(R+2)+((R+2)+2)=36 add like terms
3R+6=36 subtract 6
3R=30 divide by 3
R=10
.
check
R=10
b=12
c=14
10+12+14=36
36=36
