Answer: Choice C</h3>
2,094 cm^3
==========================================================
Explanation:
The diameter of 20 cm divides in half to the radius r = 10 cm.
The height is h = 20 cm.
V = volume of the cone
V = (1/3)*pi*r^2*h
V = (1/3)*pi*10^2*20
V = 2,094.3951023932 is approximate
I used my calculator's stored version of pi when computing the volume
That value then rounds to 2,094 cm^3 when rounding to the nearest whole number.
The third answer is the correct answer i just had that question
Answer:
5(3n - 4)(3n - 10)
Step-by-step explanation:
15n² - 110n + 200 ← factor out 5 from each term
= 5(3n² - 22n + 40) ← factor the quadratic
consider the factors of the product of the coefficient of the n² term and the constant term which sum to give the coefficient of the n- term.
product = 3 × 40 = 120 and sum = - 22
the factors are - 12 and - 10
use these factors to split the n- term
3n² - 12n - 10n + 40 ( factor the first/second and third/fourth terms )
3n(n - 4) - 10(n - 4) ← factor out (n - 4) from each term
(n - 4)(3n - 10)
then
15n² - 110n + 200 = 5(n - 4)(3n - 10)
