The area of a square with sides of length s is
A=s^2, and we are told A=25 so
s^2=25
s=√25
s=5m
(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:
<h3> 10,450</h3>
Step-by-step explanation:
21-13=8 and 29-21=8
So this is aritmetic series where a₁ = 13, and r = 8
Sum of the first n terms:
