Hello! The formula for the volume of a cone is πr^2h1/3. That means the volume of the cone is 1/3 of the base (squared radius * height * pi). The radius is 2 inches. 2^2 is 4. The height is 3 inches. 4 * 3 is 12. Pi is an irrational number that repeats, but we can use 3.14 as pi. 12 * 3.14 is 37.68. Keep in mind that this is an answer choice, but it is not the answer. We have to divide that by 3 to find the actual area, because the area of the cone is 1/3 of the base. 37.68/3 is 12.56. There. The volume of the cone is 12.56 cubic inches. The answer is A.

Answer:

The answer is D.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

$3 {q}^{2} + {r}^{3} + 5r - 8q + 2( {q}^{2} + r)$

$= 3 {q}^{2} + {r}^{3} + 5r - 8q + 2 {q}^{2} + 2r$

Next you have to simplify by collecting like terms :

${r}^{3} + 3 {q}^{2} + 2 {q}^{2} + 5r + 2r - 8q$

$= {r}^{3} + 5 {q}^{2} - 8q + 7r$

What is the value of the 1 in 178

Igoryamba

The value of 1 in 178 is 100 since it is in the hundreds place. The value of 7 in 178 is 70 and the value of 8 in 178 is 8. The hundreds place carries numbers from 1 to 9. Once you get to 10, you add a digit to the number such that you now have four total numbers and the first digit is in the thousands place.
