Answer: 1.4 inches

Step-by-step explanation:

The volume of cone is given by :-

$V=\dfrac{1}{3}\pi r^2 h$ , where r is radius and h is height of the cone.

Given: Volume of cone = 6 cubic inches

Radius =2 inches

Let h be the height of the cone .

Then , the volume of the cone will be :-

$6=\dfrac{1}{3}(3.14) (2)^2(h)\\\\\Rightarrow\ h=\dfrac{6\times3}{(3.14)(2)^2}=1.433121019\approx1.4$

Hence, the height of the cone = 1.4 inches

Ameeta finished 12 math problems. David finished 3 times as many. How many more math problems did David finish than Ameeta?

Volgvan

Answer:
david finished 24 problems more than ameetha
Step-by-step explanation:
problems finished by ameetha = 12 problems
problems finished by ameetha = 12 problemsproblems finished by David = 3 times more than ameethas problem = 3*12 = 36
problems finished by ameetha = 12 problemsproblems finished by David = 3 times more than ameethas problem = 3*12 = 36the problems finished by David more than ameetha =
problems finished by ameetha = 12 problemsproblems finished by David = 3 times more than ameethas problem = 3*12 = 36the problems finished by David more than ameetha =36-12= 24
problems finished by ameetha = 12 problemsproblems finished by David = 3 times more than ameethas problem = 3*12 = 36the problems finished by David more than ameetha =36-12= 24 so David finished 24 problems more than ameetha

The area of a pentagon increased by 27 is the same as four times the area of the pentagon, minus 15. what is the area of the pen

Basile [38]

Set up an algebraic equation. This is what it looks like based on what the question tells you:

Let a = area of pentagon
a+27 = 4a-15
3a-15 = 27
3a = 42
a = 14
