## anonymous one year ago What is the area of a sector with measure of arc equal to 90° and radius equal to 1 foot? A.) 0.25π sq ft B.) 0.5π sq ft C.) π sq ft

1. MrNood

the area of a sector is o.5 r^2 times the angle BUT the angle must be in radians there are 2 pi radians in a full circle So how many radians in 90 deg? (leave it as a value of pi)

2. anonymous

could you help me out more!?

3. MrNood

$Area = \frac{ r ^{2}\theta }{ 2 }$ what fraction of a circle is 90 deg ? (eg one half, one third, one sixteenth???)

4. anonymous

So it would be B?
