a bicycle wheel makes 5000 revolution in moving 11km .find the circumference and the diameter of wheel
Answers
Answer:
0.7
Step-by-step explanation:
total distance travel = 11 km=11000 m
total distance travel = 11 km=11000 mDistance traveled = no. Of revolutions × 2πr
Where ,r= radius of the wheel=d/2=diameter/2
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,11000 =5000 × 2π d/2
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,11000 =5000 × 2π d/211000/5000 = 22 /7×d {π= 22 /7 }
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,11000 =5000 × 2π d/211000/5000 = 22 /7×d {π= 22 /7 }11 /5 × 7 /22 = d
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,11000 =5000 × 2π d/211000/5000 = 22 /7×d {π= 22 /7 }11 /5 × 7 /22 = d7 /( 5×2)= d
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,11000 =5000 × 2π d/211000/5000 = 22 /7×d {π= 22 /7 }11 /5 × 7 /22 = d7 /( 5×2)= d7 /10 = d
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,11000 =5000 × 2π d/211000/5000 = 22 /7×d {π= 22 /7 }11 /5 × 7 /22 = d7 /( 5×2)= d7 /10 = d0.7 meter = d
Where ,r= radius of the wheel=d/2=diameter/2Now we start calculation,11000 =5000 × 2π d/211000/5000 = 22 /7×d {π= 22 /7 }11 /5 × 7 /22 = d7 /( 5×2)= d7 /10 = d0.7 meter = dTherefore, diameter of the wheel is equal to 0.7 meter
