1. Set X days to weave ordinary straw hats and Y days to weave craft straw hats.

32x+27y=300

30(x+y)=300

Solve the equation X=6.

y=4

Therefore, the production process of straw hats is 4*27= 108 tops.

2. The sector area of a 45-degree triangle in the garden+half of the circular area-the area of the triangle.

45/360π*5*5+ 1/2(π*5*5- 10* 10)= 100π
