Answer:
Jay's estimate is closer to the actual weight of the basketball
Step-by-step explanation:
The standard weight of an NBA basketball is 1.4 pounds.
Judging the accuracy of Jay's and Shawna's answer based on their percentage error when compared with the standard, we have that Jay's answer has a lower error as shown below
Error = (Standard value - Estimated value)/ Standard Value ×100
Error in Jays answer = × 100 = 64.28 %
Error in Shawna's answer = × 100 = 96.42%
From this, It is obvious that Jay's answer has a lower percentage error when compared to the actual value.
Answer: Radius = 10 cm and Arc length = 5 cm
Step-by-step explanation:
The area of a sector with radius r and central angle (In radian) is given by :-
Given : A sector of a circle has area and central angle 0.5 radians.
Let r be the radius , then we have
Thus, radius = 10 cm
The length of arc is given by :-
Hence, the length of the arc = 5 cm
