Answer:
x=2
Step-by-step explanation:
3^2x = 81
3^2x = 3^4
Compare powers
2x = 4
x = 2
1.4
1 = 100
1.4 = 140
Solution: 140%
Answer:
x=3 and y=12
Step-by-step explanation:
equation:1
equation:2
Solving equation:1 for 'y' in terms of x
equation:3
Putting 'y' in equation:2 which will make the equation of the single variable


Putting value of 'x' in equation:3 to find 'y'


The volume of ball is 113.04 cubic centimeter
<em><u>Solution:</u></em>
Given that we have to find the volume of tennis ball
Since the ball is of sphere shape, we can use the sphere formula
<em><u>The volume of sphere is given by formula:</u></em>

Where, "V" is the volume and "r" is the radius
Given that,
Diameter = 6 cm
Therefore,

<em><u>Substituting in formula, we get</u></em>

Thus volume of ball is 113.04 cubic centimeter
