Question

The diameter of a circle is 62cm

Answer 1

Answer is 3017.5 cm^2
Reason

We know diameter is 62
Radius (r) is 1/2 of diameter so r=31

Formula for area
A= pi r^2
Fill in what we know
A= (3.14) (31^2)
Multiply
A=3017.54
Round to 1 dp
A= 3017.5

Answer 2

Step-by-step explanation:

Area = 22/7¥r²

Area = 3.14 × 31cm × 31cm
