Question

BARRIERS ARE PLACE AROUND TREES FOR EACH INCH OF TRUNK DIAMETER,
THE PROTECTION ZONE SHOULD HAVE A RADIUS OF 4/3 FEET FIND THE AREA
OF THE ZONE FOR A TREE WITH A TRUNK CIRCUMFERENCE OF 63 INCHES

Shubham Chourasiya · Accepted Answer

circumference = 2(pi) r = 63 inch
i e r = 63/2(pi) = 10 0
Protection Zone = 4/3 feet = 16 inch
Now the radius of protection zone will be R = 10 +16 = 26 inch

Area of Total zone = 2(pi)26 = 163 28 inch 2

Hope this would have cleared your doubt

BARRIERS ARE PLACE AROUND TREES. FOR EACH INCH OF TRUNK DIAMETER, THE PROTECTION ZONE SHOULD HAVE A RADIUS OF 4/3 FEET. FIND THE AREA OF THE ZONE FOR A TREE WITH A TRUNK CIRCUMFERENCE OF 63 INCHES.
