What type of an equation are u looking for y-x?
Area=pi times radius^2
the 28 is a diameter
radius is 1/2 of diameter
28/2=14
area=pi times 14^2
pi=22/7 for this quesiton
area=22/7 times 14^2
area=22/7 times 196
area=4312/7
area=616 cm^2
answer is 616 square centimeers
Question 1)
Area of circle = πr²
Area of circle = π(12)² = 452.4 in² (nearest tenth)
Question 2)
Area of circle = πr²
Area of circle = π(14)² = 615.8 km² (nearest tenth)
The inequality for the given condition is x ≥ 42 inches
<u>Solution:</u>
Given that, the condition is you must be at least 42 inches tall to ride the bumper cars at an amusement park.
We have to write an inequality that represents this situation.
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =
Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥
Let "x" represent the heights of people who are allowed to ride the bumper cars
Height of people who are allowed to ride the bumper cars should be at least 42 inches
Height of people ≥ 42 inches [ since at least condition holds even at 42 value also ]
x ≥ 42 inches
Hence, the inequality for the given condition is x ≥ 42 inches
