One edge of a cube measures 3.4 meters. What is the volume of the cube? Enter your answer, as a decimal, in the box.
alina1380 [7]

The formula to find the volume multiplies the length by the width by the height.A cube has all edges the same length .If we multiply the edges three times we get the volume of any cube.

Volume of cube with sides a is Volume V= a^{3}

In the question the cube is having an edge of 3.4 meters

Volume V= 3.4^{3} =(3.4)(3.4)(3.4)=39.3

Volume of cube is 39.3 cubic meters.

The volume of a right circular cone is 2,279.64 in cubed. If the height of the cone is 18 in, what is the diameter of the cone?
Aleksandr [31]

ANSWER

A. 22 in

EXPLANATION

The volume of a cone is calculated using the formula:

Volume =  \frac{1}{3}  \times \pi {r}^{2} h

It was given that: the volume is 2,279.64 in³

The height of the cylinder is also given as: h=18 in.

We substitute, the given values into the formula to get:

2279.64=  \frac{1}{3}  \times (3.14) \times {r}^{2}  \times 18

2279.64= 18.84 {r}^{2}

{r}^{2}  =  \frac{2279.64}{18.84}

{r}^{2}  = 121

We take positive square root to get;

r =  \sqrt{121}

r = 11in

Therefore the diameter is 2(11) which is equal to 22 inches.

The time spent to travel a certain distance varies inversely as a car's speed. If it takes 5½ hours to travel a certain distance
Licemer1 [7]

Answer:

6.6h

Step-by-step explanation:

  • So it takes 5.5 hours going at a speed of 60 miles per hour, multiply these two and we get a distance of 330 miles
  • Use this distance to find the time if speed is 50 miles per hour, so time is derived by dividing the distance by the speed
  • 330 miles divide by 50 miles per hour gives 6.6 hours

PLEASE HELP IMMEDIATELY!!!! Find x when – Negative one-half + x = –Negative StartFraction 21 over 4 EndFraction. – Negative Star
balu736 [363]

Answer:

-61/4

Step-by-step explanation:

-1/2 + x = - 21/4 - 23/4 - 19/4

-1/2 + x = -(21+23+19)/4

x = -63/4 + 1/2

x= -63/4 + 2/4

x = -61/4

Hope that helps, tell me if you need further explanation. =)
