Answer:
parentage error in calculated value of radius of circular plate will be 2.5 %
Explanation:
Pressure = Force / Area
=> Area = Force / Pressure
=> π Radius² = Force / Pressure
2ΔR/R = ΔF/F + ΔP/P
=> 100 * 2ΔR/R = 100 * ΔF/F + 100 * ΔP/P
=> 100 * 2ΔR/R = 4 + 1
=> 100 * ΔR/R = 5/2
=> 100 * ΔR/R = 2.5
parentage error in calculated value of radius of circular plate will be 2.5 %
