Answer:
Linear pairs are congruent
That's the answer
<span>( 9 + 2 i ) ( 3 − 5 i ) − ( 9 + i ) ( 3 − 5 i )
FOIL
i x i = -1
(27 + 6i - 45i +10) - (27 +3i - 45i +5)
Combine like terms and distribute the negative
37 - 39i + 42i - 32
3i + 5
This is the farthest I could go with it. Assuming you were looking for a simplification though you did not specify your desired answer's criteria. Hope this helped!</span>
area = pi x r^2
circumference = 2x pi x r or pi x d
1st one diameter = 9.5 cm
so radius = 9.5/2 = 4.75
area = 3.14 x 4.75^2 = 70.85 square cm
circumference = 3.14 x 9.5 = 29.83 cm
2nd one radius = 4
area = 3.14 x 4^2 = 50.25 square cm
circumference = 2 x 3.14 x 4 = 25.12 cm
Area of base = 1/2 x 18 x 15.6 = 140.4
140.4 x 22 = 3088.8 cubic cm
