Area of a trapezoid = h/2 ( a + b) where h = height and a and b are the lengths of the 2 parallel sides.
So here we have
Area = 12/2 ( 18 + 23)
= 246 in^2 Answer
ii . volume of a sphere = 4/3 pi r^3 so
1436.03 = 4/3 pi r^3
r^3 = 1436.03 / (4/3 * pi) = 342.827
r = cube root of 342.827 = 7.0 m Answer

Answer:
4a2−4ab+b2
Step-by-step explanation:
(2a−b)2 =(2a+−b)(2a+−b)
=(2a)(2a)+(2a)(−b)+(−b)(2a)+(−b)(−b)
Sooo our equation =4a2−2ab−2ab+b2
