Question

Area sector
Radius
42 cm and angle 30'
is how many
Sq cm ?

Answer 1

Answer:

147π cm^2 OR 461.81 cm^2

Step-by-step explanation:

Formula for Area of circle:  $\pi r\x^{2}$

But since it is a sector, so 30 degrees over 360 degrees (Full circle angle) multiplied with the area of the circle of radius 42 cm. You are getting the fraction of the sector from a full circle with those dimensions.

So, just input into formula:

$\frac{30}{360}$ x $\pi (42)^{2}$ = 147π $cm^{2}$ OR 461.81 $cm^{2}$
