Answer:
38.485(correct to 5 significant figure)/ 12.25π
Step-by-step explanation:
![\pi(7 {}^{2} )( \frac{90degree}{360deree} )](https://tex.z-dn.net/?f=%5Cpi%287%20%7B%7D%5E%7B2%7D%20%29%28%20%5Cfrac%7B90degree%7D%7B360deree%7D%20%29)
![= \pi(49)( \frac{1}{4} )](https://tex.z-dn.net/?f=%20%3D%20%5Cpi%2849%29%28%20%5Cfrac%7B1%7D%7B4%7D%20%29)
=38.485(cor. to 5 sig.fig.)/ 12.25π
