Mathematics

The circumference is merely increased by 50%. The formula for a circle (which I assume you know) is 2*pi*r. Work out this value, then multiply it by 1.5. You get the same answer as multiplying 2*pi*(r*1.5). Just fyi (if you didn't know), multiplying something by 1.5 increases it by 50%, multiplying something by 1.12 increases something by 12% etc.

yan [13]

Answer:

The answer is 12a^3+2a²+23a+18 ....

Step-by-step explanation:

The given terms are:

(3a + 2)(4a² - 2a + 9)

Now multiply each value of second bracket with the first bracket:

=4a²(3a+2) -2a(3a+2)+9(3a+2)

=12a^3+8a²-6a²-4a+27a+18

Solve the like terms:

=12a^3+2a²+23a+18

Therefore the answer is 12a^3+2a²+23a+18 ....
