5 0

Answer:

12 mph

Step-by-step explanation:

Speed = distance/time

Distance = 20.4 miles
Time = 17 minutes = 17*1/60 hours = 17/60 hours

Speed is:

20.4 : 17/60 =
20.4*60/17 =
72 mph

Alyn exceeded the limit by:

72 - 60 = 12 mph

The circumference of a circle is 15 pie centimeters. What is the area of the circle in terms of pie

Jobisdone [24]

Answer:

Step-by-step explanation:

The circumference (C) of a circle = 2πr ← r is the radius

Given C = 15π the equating gives

2πr = 15π ( divide both sides by 2π )

r = $\frac{15}{2}$ = 7.5 cm

The area (A) of a circle is calculated using the formula

A = πr² = π × 7.5² = 56.25π cm² → C
