In order to solve this question, you need to look at the common multiples of both 15 and 24.
Multiples of 15: 15, 30, 45, 60, 75, 90, 105, 120, 135
Multiples of 24: 24, 48, 72, 96, 120, 144
If you observe, both 15 and 24 are multiples of 120. Therefore the 120th customer will be the first customer to win both prizes.
You use a Protractor and measure it in the centre.
4 goes into all of them
4*4=16
4*6=24
4*10=40
Answer: 258.31 cm²
<u>Here it's given that ,</u>
- Circumference of the circle = 57cm.
<u>To Find ,</u>
We know that ,
→ Circumference = 2πr
Substituting the respective value ,
→ 57cm = 2πr
→ r = 57cm/2π
→ r = 57/(2*3.14) cm
→ r = 9.07 cm
And ,
→ Area = πr²
→ Area = 3.14 * (9.07cm)²
→ Area = 3.14 * 82.26 cm²
→ Area = 258.31 cm²
<u>Hence</u><u> the</u><u> </u><u>area</u><u> of</u><u> the</u><u> circle</u><u> is</u><u> </u><u>2</u><u>5</u><u>8</u><u>.</u><u>3</u><u>1</u><u> </u><u>cm²</u>
I hope this helps.
