Question

CIRCLE question is in the picture

Answer 1

Answer:

27π cm² or 84.8 cm²

Explanation:

$\sf Formula \ for \ area \ of \ sector = \dfrac{\theta}{360 } \ x \ \pi (radius)^2$

Shaded region angle: 360° - 90° = 270°

 Given radius: 6 cm

Applying formula:

$\rightarrow \sf \dfrac{270}{360} \ x \ \pi (6)^2$

$\rightarrow \sf 27\pi$

$\rightarrow \sf 84.823 \ cm^2$

$\rightarrow \sf 84.8 \ cm^2 \quad (rounded \ to \ nearest \ tenth)$
