2x-7 i think not 100% shure
By the question,
π = 3.14
circumference = 7.42 cm
or,. 2πr. =7.42
or,. 2×3.14×r. =7.42
or,. 6.28r. =7.42
or,. r. =7.42÷6.28
∆. r. =1.18 cm
Again,
Area of circumference= πr^2
=3.14 × 1.18^2
=3.14 × 1.39
=4.37 cm^2
Answer:
Change in temperature = - 3.3 F
The temperature has decreased
Step-by-step explanation:
The complete question is attached below .
As given in the attached image
Temperature at 10 A.M 
degree Fahrenheit
Temperature at 3:30 P.M. 
degree Fahrenheit
Change in temperature
= Temperature at 3:30 p.m - Temperature at 10 a.m
= 
F
The temperature has decreased
Answer: 62.
Step-by-step explanation: The mean is the average. In order to find the average, we need to add all of the numbers up, then divide by the number of quizzes. So:
20 + 40 + 40 +40 + 60 + 60 + 60 + 60 + 80 + 80 + 80 + 80 + 100 = 800
800 / 13 = 61.5, appr. 62.
