An area of 3.5m² is the same as 350000mm². True or false. Justify your answer

Vsevolod [243]

No, because to convert meter to millimeter you'll have to multiply the length value by 1000 which will give you 3500.

3.5 × 1000

= 3500.

have a great day!

What is the approximate circumference of the circle shown below?

Crank

Answer

Formula

$Circumference\ of\ circle = 2\pi r$

where r is the radius of a circle.

As shown in the image

Diameter of the circle = 16 .3 cm

$Radius\ of\ the\ circle = \frac{16.3}{2}$

= 8.15 cm

Put in the formula

$Circumference\ of\ circle = 2\pi\times 8.15$

$\pi = 3.14$

$Circumference\ of\ circle = 2\times 3.14\times 8.15$

= 51.2 cm (approx)

Therefore the circumference of a circle is 51.2cm (approx) .

Option (D) is correct .
