Work out the area ofthis circle. Take pie to be 3.142 and give your answer to 1 decimal place. No working out needed

50.3 cm²

Step-by-step explanation:

==>Given:

Circle with radius = 4cm

π = 3.142

==>Required:

Area of the circle

==>Solution:

Area of circle can be calculated using the formula:

Area = πr²

Area = 3.142 × r²

Area = 3.142 × 4 × 4

Area = 3.142 × 16

Area = 50.272 cm²

Round off answer to 1 decimal place:

Thus, area of circle approximated to one decimal place = 50.3 cm²
