Question

The area of a circle whose diameter is 1.4 cm is

• A. $1.54c{m}^2$
• B. $0.77c{m}^2$
• C. $6.16c{m}^2$
• D. None of these

Answer 1

The correct option is A $1.54c{m}^2$

Area of cirlce

$=\pi r^2$

$=\pi {\left(\frac{d}{2}\right)}^2$

$=\frac{22}{7}{\left(\frac{1.4}{2}\right)}^2$

$=1.54m^2$
