Answer:
Step-by-step explanation:
Area = pi r^2 if 3 is the radius
pi (3)^2 = 9 pi in^2
if 3 is the diameter then radius = 1.5
pi r^2 = pi (1.5)^2 in^2

Answer:
Like Earth, Mars has frozen polar caps, but unlike Earth, these caps are made of carbon dioxide ice as well as water ice. so d is correct
Answer:
Solution of the expression is 1.07
Step-by-step explanation:
The given logarithmic expression is 
Since change of base formula says, 
Therefore, the given expression can written as
by using change of base formula.
Now 
= 1.069
≈ 1.07
Therefore, solution of the expression will be 1.07
we need some barriers such that total of length of all barriers should equal to the circumference of the circle.
so lets assume we need x barriers
then total length of all barriers = 2.5x meter
now radius of circular path = diameter / 2= 13/2 = 6.5 meter
circumference of path = 2× pi × r = 2 × 3.14 × 6.5
=40.82 meter
so now as per statement
2.5x = 40.82
x = 40.82/2.5 = 16.328 ≈ 17
so approximately 17 barriers are required
