Question

Find the perimeter of the quadrant whose radius is 28cm​

Answer 1

Answer:

$\huge\boxed{Perimeter = 99.98\ cm}$

Step-by-step explanation:

Quadrant is one - fourth of a circle

Perimeter of quadrant = $\frac{2\pi r }{4} + 2r$

Where r = 28 cm

=> P = $\frac{2(3.14)(28)}{4} + 2(28)$

=> P = $(3.14)(14) + 56$

=> P = $43.98 + 56$

=> P = 99.98 cm

Answer 2

Answer:

$\huge \boxed{\mathrm{99.98 \ cm}}$

Step-by-step explanation:

A quadrant is quarter of a circle.

The perimeter of a quarter of a circle is $\frac{2\pi r}{4} +2r$.

The radius $r$ is 28 cm.

$\frac{2\pi (28)}{4} +2(28)= 99.982297...$

The perimeter of the quadrant with radius 28 cm is approximately 99.98 cm.
