Answer:
ANSWERS:
1) 7.065 cm²
2) 132.665 cm²
3) 283.385 m²
4) 530.66 m²
5) 1384.74 m²
FORMULA:
A = πr²
MEANINGS:
A means area
π means pi or 3.14 (rounded)
r means radius
HOW TO CHANGE THE DIAMETER INTO RADIUS TO FIND THE AREA OF A CIRCLE?:
Just divide the diameter by two to get the radius.
SOLUTION:
1. A = πr²
A = (3.14)(1.5 cm)²
A = (3.14)(2.25 cm²)
A = 7.065 cm²
2. A = πr²
A = (3.14)(6.5 cm)²
A = (3.14)(42.25 cm²)
A = 132.665 cm²
3. A = πr²
A = (3.14)(9.5 m)²
A = (3.14)(90.25 m²)
A = 283.385 m²
4. A = πr²
A = (3.14)(13 m)²
A = (3.14)(169 m²)
A = 530.66 m²
5. A = πr²
A = (3.14)(21 m)²
A = (3.14)(441 m²)
A = 1384.74 m²
