Mathematics Question and Solution
Calculating Area Blue.
It implies;
A1 = 64π cm², therefore radius A1, x = 8 cm.
A2 = 32π cm², therefore radius A1, y = 4√(2) cm.
A3 = (16/3)π cm², therefore radius A1, z = 4/√(3) cm.
Therefore;
Area blue is;
Area triangle with two length 10.3094010768 cm and 7.96625532625 cm, and angle 95.85811003° - Area sector with radius (4/√(3)) cm and angle 95.85811003° - Area sector with radius 4√(2) cm and angle 48.6724043189° -Area sector with radius 8 cm and angle 35.4694856511°.
= ½*10.3094010768*7.96625532625sin95.85811003 - 95.85811003÷360*π(4/√(3))² - 48.6724043189÷360*π(4√(2))² - 35.4694856511÷360*π*8²
= 40.8492140584 - 4.46143902603 - 13.5918993636 - 19.8098978752
= 2.9859777936 cm²
