Answer:
Step-by-step explanation:
<u>Area of circle:</u>
<u>Circumference of circle:</u>
<u>Given</u>
<u>Find r using the second formula:</u>
- 2πr = 55
- 2*3.14r = 55
- r = 55/6.28
- r = 8.8 (rounded)
<u>Find area using the first formula:</u>
- A = 3.14*8.8²
- A = 243 m² (rounded)
V = d/t
75 km/h = 480km /t
t = 480km / 75 km
t = 6.4 hours or 384 minutes
