Volume of ball = 13.39 inch ^3 Volume of ball = 4/3 X pi x r^3 ATQ 4/3 X pi X r^3 = 13.39 4/3 X 22/7 X r^3 = 13.39 r^3 = 13.39 x 7/22 x 3/4 r^3 = 281.19/88 r^3 = 3.19 r = 1.47 inches d = 2 x 1.47 = 2.94 inches
Answer: 225
<u>Step-by-step explanation:</u>
n₁ = 2(1) - 1
= 2 - 1
= 1
n₁₅ = 2(15) - 1
= 30 - 1
= 29
= 15 * 15
= 225
To simplify the expression, we distribute terms accordingly. It is done as follows:
<span>(3a – 4b)(a + b)
3a</span>² + 3ab -4ab -4b²
3a² - ab -4b²
Therefore, the correct answer is option A, <span>3a^2– ab – 4b^2.
