a circular platform has a circumference of 308 feet , determine the area of the platform
Accepted Solution
A:
Answer:A = 7552.866242 ft^2Step-by-step explanation:Circumference = 2 * pi *r308 = 2 * pi *rDivide each side by 2154 = pi *rDivide each side by pi154/pi = pi *r/ pi154/pi = rThe area of a circle is given byA = pi r^2A = pi * (154/pi)^2A = pi * 154/pi * 154/piA = 154*154 /piA =23716/piLet pi be approximated by 3.14A = 23716/3.14A = 7552.866242 ft^2
