Answer:
1/21
Step-by-step explanation:
The baker makes 84 loaves of bread,
Out of the 84 bread, 4 of them got burn.
Fraction that the loaves does the burn will be expressed in 4/84 = 1/21.
Answer:
18π
Step-by-step explanation:
You have to multiply the height and the width together and then multiply by pi but since it is in terms of pi it is 18π

Answer and Explanation:</h2><h2 />
The density of a substance is defined as its mass per unit volume. In a mathematical language, this can be written as follows:

From the problem, a student is trying to calculate the density of a ball. She already knows the mass, but is facing a problem because she also needs to find the volume. From geometry, we know that the volume of a sphere is:

Since a ball is a sphere, then the student can use this formula. She just need to measure the radius of the ball and compute the Volumen, then she have to plug both the value of the mass and the value of the Volume in the equation
. An easy way to find the radius is to take the measure of the diameter of the ball and divide that value by 2.
Given that a = 2, b = 3, and c = 4.
To evaluate ab+c, we will plug given values as shown below
ab+c
=2*3+4
=6+4
=10
Hence final answer is 10.
