Answer 1

Answer:

Step-by-step explanation:

Answer 2

The area of a circle whose radius is 10.5 cm is 346.5 cm².

Given: Radius of a circle = 10.5 cm

To find: Area of a circle

Formula used:

Area of circle  = πr²

Here, 'r' is the radius of a circle

Solution:

Area of circle  = πr²

Area of a circle = $\frac{22}{7} \times 10.5\ cm \times 10.5 \ cm$

[pie (π) = 22/7]

Area of a circle = 22 × 1.5 cm × 10.5 cm

Area of a circle = 33 cm × 10.5 cm

Area of a circle = 346.5 cm²

Hence, the area of a circle is 346.5 cm².
