K = phi x r x r
K = 22/7 x 21 x 21
K = 22 x 3 x 21
K = 66 x 21
k = 1.386
2. Luas segitiga
L = a x t
L = 4 x 8
L = 32.
3. Keliling trapesium
K = s1 + s2 + s3 + s4
k = 20 + 16 + 16 + 16
k = 36 + 32
k = 68
4. Luas permukaan kubus .
6 x s x s
6 x 28 x 38
= 6 x 784
= 4.704 cm
5. Volume tabung
V = phi x r x r x t
v = 22/7 x 14 x 14 x 35
v = 22 x 7 x 14 x 35
v = 154 x 24 x 35
v = 3.696 x 35
v = 129.360 cm
