Answer: A) 6250, 2500
<u>Step-by-step explanation:</u>
Factor the numbers. What they have in common is the GCF.
The GCF times everything leftover is the LCM.
6250: 5 × 5 × 5 × 5 × 5 × 2
2500: 5 × 5 × 5 × 5 × 2 × 2
What they have in common is the GCF:
6250: <u>5 × 5 × 5 × 5</u> × 5 × <u>2</u>
2500: <u>5 × 5 × 5 × 5</u> × 2 × <u>2</u>
GCF = 5 × 5 × 5 × 5 × 2 = 1250
GCF times everything leftover is the LCM:
6250: 5 × 5 × 5 × 5 × <u>5</u> × 2
2500: 5 × 5 × 5 × 5 × <u>2</u> × 2
LCM: 1250 × 5 × 2 = 12500
Question 1)
Area of circle = πr²
Area of circle = π(12)² = 452.4 in² (nearest tenth)
Question 2)
Area of circle = πr²
Area of circle = π(14)² = 615.8 km² (nearest tenth)
