I believe that the answer would be to add 10 to both sides, srry if I'm incorrect!
<span>The shortest path from a starting point to an endpoint, regardless of the path taken, is called the </span>geodesic. In flat (Euclidean) space it is simply a straight line.
This may be the answer,hope it helps
(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)
