1 liter of petrol costs 60 Rs the car can run 121 km using 11 liters of petrol how much does it cost for 143 km

780 Rs

Step-by-step explanation:

Work out how far 1 litre of petrol will take you - we know the car goes 121 km on 11 litres, so 121/ 11 = 11. Therefore the care goes 11km per litre of fuel.Find how many litres of fuel are needed to go 143 km: 143/ 11 = 13, so the car needs 13 litres of fuel.Find how much this costs: we have 13 litres at 60 Rs each. So 13 x 60 = 780 Rs

Answer: 10pi

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

put like terms together.orremember that the 45 becomes negative when moved to the other side.orthe minuses cancel out.
