The wheels of a bicycle have a diameter of 70cm. How many meters will the bicycle travel if each wheel makes 50 revolutions
2 answers:
Answer:
see explanation
Step-by-step explanation:
1 revolution is equivalent to the circumference of the wheel
1 revolution = πd ( d is the diameter )
= 70π cm
50 revolutions = 70π × 50 = 3500π cm = 35π m ≈ 110m ( nearest metre )
Answer:
109.956 m
Step-by-step explanation:
The first step is to find the circumference of the wheel.
C = πd
where d = diameter of the wheel
C = πd
= π × 70
= 219.9 cm.
In every revolution the bicycle move 219.9 cm.
In 50 revolution the bicycle will make = 219.9 × 50
= 10,995.6 cm
In meter = 10,995.6 ÷ 100
= 109.956 m

<u>Explanation</u>
(2a - 3b)¹⁰ = (2a)¹⁰ - 10(2a)⁹(3b) + 47(2a)⁸(3b)² - 144(2a)⁷(3b)³ - 212(2a)⁶(3b)⁴ + 352(2a)⁵(3b)⁵
The 6th term in this expression is 352(2a)⁵(3b)⁵
352(2a)⁵(3b)⁵ = 352 × 2⁵a⁵ × 3⁵b⁵
= 352 × 32 ×243 ×a⁵b⁵
= 2,737,152a⁵b⁵
