Answer:
I. Circumference of circular flower bed = 31.42 ft.
II. Area of circular flower bed = 78.55 ft²
Step-by-step explanation:
Given the following data;
Diameter = 10 ft
Radius = diameter/2
Radius = 10/2
Radius, r = 5 ft
I. To find the circumference of the circular flower bed;
Circumference of circle = 2πr
Substituting into the formula, we have
Circumference of circular flower bed = 2*3.142*5
Circumference of circular flower bed = 31.42 ft
II. To find the area;
Area of circle = πr²
Substituting into the formula, we have;
Area of circular flower bed = 3.142*5²
Area of circular flower bed = 3.142*25
Area of circular flower bed = 78.55 ft²
Assuming the length is y and the width is x
Perimeter = y + y + x + x
= 2y +2x
= 2 (y + x)
if the is 8 and the perimeter is 108
108 = 2 (y +8)
108/2 = y+8
54 = y +8
54 - 8 = y
46 = y
Length = 46 inches
Answer:
7500. There are 100 centimeters in a meter therefore 75 meters have 7500 centimeters.
