The density of water is 1 gram per cubic centimeter. a more dense object will sink, and a less dense object will float. will a marble with a radius of 1.4 cm and a mass of 9 grams sink or float in water?

We need to know the density of the marble to know whether it will float or sink. If density is less than 1, it will float. If density more than 1, it will sink

Density  = mass divided by volume

Given:

Since marble is spherical, we use formula for volume of  sphere

Volume of sphere =

since r = 1.4, we find the volume of marble:

Volume of marble =

Now, finding density:

If , the object will float.

Since , the marble will float.

ANSWER: Float

●yes, this statement is absolutely apt.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
