Answer:

Circumference: 14π square inches or approximately 43.96 square inches

Area: 49π square inches or 153.86 square inches

Step-by-step explanation:

Circumference = 2πr, where r = radius

2π(7) = 14π or 14(3.14) = 43.96

Area = πr^2, where r = radius

π7^2 = 49π or 49(3.14) = 153.86

Answer:

the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour

Step-by-step explanation:

The computation of the standard deviation of the speeds of cars is shown below;

The z score for the top 1% is 2.326

So,

= (75 - 61) ÷ standard deviation = 2.326

Standard deviation is

= 14 ÷ 2.326

= 6.0 miles per hour

Hence, the standard deviation of the speeds of cars travelling on California freeways is 6.0 miles per hour
