Answer:

452.16 in³

Step-by-step explanation:

A volcano is an inverted cone and with that, the volume can be solved through the equation,

V = (1/3)(area of the base)(height)

We solve the area of the base first,

area of the base = (pi)(r²)

= 3.14(6 in)²

= 113.04 in²

Substituting these calculated values and the other givens above to the first equation,

V = (1/3)(113.04 in²)(12 in) = 452.16 in³

Thus, the volume of the model is approximately equal to 452.16 in³.

3 − m = −2 (m + 6); m = −15 Yes or No

Nimfa-mama [501]

Answer:

3 − m = −2 (m + 6); m = −15 Yes

5 (p + 3) = −35; p = −4 No

8q = 3 (10 + q); q = 6 Yes

Step-by-step explanation:

3 − m = −2 (m + 6)

3 - m = -2m - 12

m = -15

Answer is Yes

5 (p + 3) = −35

5p + 15 = -35

5p = - 50

p = -10

Answer is No

8q = 3 (10 + q)

8q = 30 + 3q

5q = 30

q = 6

Answer is Yes

Which best describes the meaning of the statement if A then B

Oliga [24]

Answer:

$a => b \equiv ( \neg a \ \lor \ b )$

Step-by-step explanation:

You can understand the statement from many perspectives, but in terms of proposition logic it is best to understand it as "negation of a" or " b" in mathematical terms is written like this

$a => b \equiv ( \neg a \ \lor \ b )$

You can show that they are logically equivalent because they have the same truth table.
