A. Find the surface area of each solid figure
1. 232 cm²
2. 57 cm²
3. 172 cm²
B. Solving word problem.
1. 864 cm²
Solution:
1. 12 x 12 x 6 = 864
2. 22608 cm²
Solution:
2. 4 x 3.14 x 30² = 22608
3. 405. 06 in²
Solution:
3. c = 2πr = 2 x 3.14 x 3 = 18.84
A = ch = 18.84 x 10 = 188.4
2A = 2x 188.4 = 376.8
πr² = 3.14 x 3² = 28.26
376.8 + 28.26 = 405.06 in²
There are 405.06 in² surface will be painted.
PS. Yung Letter A po at no. 4 nasa picture pindutin n’yo na lang po
