Is this question correct? is it thousand or thousandth? and does the comma signify a decimal point?
Answer:
C. 179 ft²
Step-by-step explanation:
Area of circular path or walkway
= π × (R + r) × width
Where
R= Outer radius
r = Inner Radius
Diameter = 16 feet
Width = 3 feet
Inner Radius = Diameter/2
= 16 feet/2 = 8 feet
Outer Radius = 8 + 3 = 11 ft
Hence:
= π × (11 + 8) × 3
= π × 19 × 3
= 179.07078125 ft²
Approximately = 179 ft²
The area of the circular walkway = 179ft²
Option C is correct.
Answer:
100m
Step-by-step explanation:
First, find the area of one triangle. Use l*w/2 to do that.
10*5=50
50/2=25
Multiply this by 4 to get the total area
25*4=100
Have a good day!
