Question

Require a little help with this please and thank you

Answer 1

Answer:

201.06 is the area

Step-by-step explanation:

With the diameter being 16cm

The radius would be 8cm, with that information using the formula

A = π x r^2

I got 201.06 cm as the area

The circumference is 50.27 cm

I hope this helps, if not sorry

Answer 2

Solution:

• Here, the length of the side of the square is 16 cm.
• Here, the circle touches the square.
• So, the diameter of the circle = 16 cm
• Therefore, radius of the circle = Diameter of the circle ÷ 2

= 16 cm ÷ 2

= 8 cm

• Area of a circle = πr^2 where r is the radius of the circle
• Therefore, area of the circle

$= \pi \times 8cm \times 8cm\\ = 3.14 \times 8cm \times 8cm \\ = 200.96 \: square cm$

Answer:

The area of the circle is 200.96 square cm.

(I have taken π as 3.14, you may take 22/7 but it will be a very long answer. So I prefer you to take π as 3.14)
