Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A =
bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A =
× 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³
A complex number is made of two parts: one real part (without i) and one imaginary part (with i).
The conjugate of a complex number is found by inverting the sign of the imaginary part of the number.
Therefore, the conjugate of 10+3i is 10−3i
Answer:
96 square centimetres
Step-by-step explanation:
3 feet= 12 centimetres
2 feet= 8 centimetres
if 1 foot equals 4 centimetres then you would multiply 3x4 to get the length and 4x2 to get the width and multiple those answers to get the final area.
