Answer:
a:b = 6:10 = 3:5 = 21:35
b:c = 21:33 = 7:11 = 35:55
a:b:c = 21:35:55
Answer:
about 214.1
Step-by-step explanation:
Since pi r squared is the formula for a circle's area, you would do the opposite. First, you would divide 144001 by pi which is about 45,836.94. Then, you would find the square root of that which is about 214.1.

Answer:
174cm^2
Step-by-step explanation:
Given data
L=9m
W=5m
H=3m
The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2
Answer:
The height of the tree is 21 ft
Step-by-step explanation:
we know that
A light post that is 9 feet tall that casts a shadow that is 6 feet long
so
by proportion
Find out the the height of the tree if a tree that casts a shadow that is 14 feet long
Let
x ----> the height of the tree
therefore
The height of the tree is 21 ft
