Answer:

Area = 95.4 cm²

Step-by-step explanation:

Given

θ = 135°

r = 9cm

Required

Calculate the area of the sector

Area of a sector is:

Area = θ/360 * πr²

Substitute values for θ and r

Area = 135/360 * π * 9²

Area = 0.375 * π * 81

Take π as 3.14

Area = 0.375 * 3.14 * 81

Are = 95.3775

Area = 95.4cm² ---- approximated

The price for a car in 2015 was RM 54000. This was 10% higher compared to the year 2014?

-Dominant- [34]

Answer:

2014 price was $49,091

Step-by-step explanation:

I'm assuming you want to solve for 2014 year price...

2015 year price is 54,000 and was 10% higher than 2014 price, meaning 2015 price is 110% of 2014 price so...

p×110%=54,000

p=54,000/1.1

p=49,090.90
