A semicircle with a radius of 5cm is divided into five parts, S, T, U, V, and W, by four straight lines. Points C, D, and E in the figure are points that divide the diameter AB into four equal parts. The size of each of the four ●-marked corners is 45 degrees. Assuming pi = 3.14, the area of S is a.bcd (cm^2), and the sum of the areas of T and V minus the sum of the areas of U and W gives e.fg (cm^2).
The cache can be found at S 42° 45.(a+f)(c+d)(e+f) E 147° 8.(b+g)(b+c)(g-c-b)
Cache is near the main road (about 3 metres away, so not a place for small children)
