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

Answer:
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
