Answer:
We use formula, circumference= 
to get r= 7.48
Step-by-step explanation:
Here is the complete question: The circumference of a pool is 47 feet. Which formula can you use to find Radius (r), if you know that C =2πr.
Given: Circumference= 47 feet.
We will use formula of circumference to find radius (r) as given.
Circumference =
⇒ 
(∵ we know π=3.14)
Cross multiplying both side to get r.
⇒ r= 
∴ radius (r)= 7.48
∴ We will use circumference formula to find Radius (r).
Answer:
Perimeter of a rectangle = 2(L + W)
Step-by-step explanation:
L = length
W = width
In a rectangle, of the four sides, there are two equal length and 2 equal width
Length = 2 sides
Width = 2 sides
perimeter of a rectangle is the sum of the lenths of its four sides.
Perimeter of a rectangle = L + L + W + W
= 2L + 2W
Factorize
= 2(L + W)
Perimeter of a rectangle = 2(L + W)
This expression shows the relationship
Answer:
The answer to your question is 68 ft²
Step-by-step explanation:
Data
Large square Small square
base 10 - 2 = 8 ft 2 ft
height 8 ft 2 ft
Process
1.- Find the area of the large square
Area = base x height
= 8 x 8
= 64 ft²
2.- Find the are of the small square
Area = base x height
Area = 2 x 2
= 4 ft²
3.- Find the total area
Total area = 64 + 4
= 68 ft²
Divide 72 by 6, and then by 9. Your answers will be there.
