Since the two triangles are proportional, there is a scale for going from one triangle to the other
Answer:
1.36 centimeters
Step-by-step explanation:
Given,
side length ( a ) = 17 mm
To find : Perimeter of regular octagon ( in cm )
Octagon has 8 sides.
Perimeter of regular octagon
= 8 x a
= 8 x 17
= 136 mm
1 mm = 0.1 cm
136 mm
= 136 x 0.1
= 1.36 centimeters ( cm )
Hence,
Perimeter of regular octagon is 1.36 centimeters.
.2 m^3 is 10 percent
.2 m^3 is 10 percent
.2 m^3 is 10 percent
.1 m^3 is 5 percent
therefore
.7m^3 is 35%
.6m^3 is 10%
.3 m^3 is 5%
so .9m^3 is 15 %
all in .9m^3 +.7m^3 = 1.6 m^3 will be sand
9 cups, 2 1/4= 2.25, 2.25 times 4 equals 9
