SOLVE NUMBER 1:
A = πr2
A = (3.14)(7)(2)
A = (3.14)(49)
A = 153.86 sq.m
Explanation
- 1st we need to used the formula of A = πr2 that A represent area and Π or pi represent 3.14 equavalent and r is the radius and the purpose of 2 is to multiply the radius
- all we need to is to multiply the π × r × 2

SOLVE NUMBER 2:
A = πr2
A = (3.14)(10)(2)
A = (3.14)(100)
A = 314 sq.in
Explanation
- 1st we need to used the formula of A = πr2 that A represent area and Π or pi represent 3.14 equavalent and r is the radius and the purpose of 2 is to multiply the radius
- all we need to is to multiply the π × r × 2

SOLVE NUMBER 3:
A = πr2
A = (3.14)(8)(2)
A = (3.14)(64)
A = 200.96 cm²
Explanation
- 1st we need to used the formula of A = πr2 that A represent area and Π or pi represent 3.14 equavalent and r is the radius and the purpose of 2 is to multiply the radius
- all we need to is to multiply the π × r × 2

Note:
- π pi is equal to 3.14
- r is tje radius
- 2 multiply the r and π
- π times r times 2 or π × r × 2
