(b)(b)=25 cm2
b2=25 cm2
√(b2)=√(25 cm2)
b= 5 cm
Please note the square root of 25 was taken, as well as the square root of cm2.
Perimeter=4b
Perimeter=4(5 cm)
Perimeter=20 cm
Step:
A circle of radius = 12.5 or diameter = 25 or circumference = 78.54 cm has an area of: 4.909 × 10-8 square kilometers (km²) 0.04909 square meters (m²)

Answer: For a fence that has 18 posts he needs 36 rails.
Step-by-step explanation:
Hi, to answer this question we have to use proportions:
Each section use 3 vertical fence post and 6 horizontal rails
The proportion is = 3 post /6 rails
For 18 posts:
18 posts / x rails.
3 /6 = 18 /x
Solving for x:
x = 18 / (3/6)
x = 36 rails
For a fence that has 18 posts he needs 36 rails.
