Answer:
The area of the circle is 113.0 ft²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 6ft
π = 3.14
a = π * r²
we replace with the known values
a = π * (6ft)²
a = π * 36ft²
a = 113.04ft²
The area of the circle is 113.04ft²
round to the nearest tenth
a = 113.04ft² = 113.0 ft²
Answer:
13. ft per minute is 150. ft per hour is 9,000.
work:
- 300÷ 2 = 150
- 150 times 60 min.
14. x ÷ y = feet per minute.
it is this because the time divided by the depth will equal the time that it took.
15. it would be more reasonable to use feet by minute, because of the accuracy of the answers. with measuring it using feet per hour, your answers will be less precise.
16. the distance will double because the proportional relationship says that the distance is 3 km away if thunder is 9 secs apart from lightning.
