Is known that
(a + b)² = a² + 2.a.b + b²
So:
(x + 4)² = x² + 2.x.4 + 4² = x² + 8x + 16
Answer:
7 + 7n
Explanation:
Seven more (7 plus) the product of 7 and a number (seven times n) = 7 plus 7n
Answer:
Volume of tennis ball = 11.49 inch³
Step-by-step explanation:
Given:
Radius of tennis ball = 1.4 inches
Value of π = 3.14
Find:
Volume of tennis ball
Computation:
Volume of sphere = [4/3][π][r]³
Volume of tennis ball = [4/3][π][Radius of tennis ball]³
Volume of tennis ball = [4/3][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][1.4]³
Volume of tennis ball = [1.333][3.14][2.744]
Volume of tennis ball = [4.1856][2.744]
Volume of tennis ball = 11.4852
Volume of tennis ball = 11.49 inch³
