Leysa 3*76=sec(0.2)^3pi/4*x

$$3 \cdot 76 = \frac { \sec ( 0.2 ) ^ { 3 } \pi } { 4 } \times x$$

Leystu fyrir x

$$x = \frac{222656250000000000000000000000000000000000000000}{244145087219074873950587129654482342313344039 \pi} = 290\frac{2.24970398929383 \times 10^{44}}{7.670044124174848 \times 10^{44}} \approx 290.293310436$$
