Answer:
13.) 314.2 in²
15.) 181.5 ft²
Step-by-step explanation:
The area of a circle is found using the equation:
A = πr²
In this equation, "π" represents the number pi (3.14....) and "r" represents the radius (half the diameter).
For 13.), you have been given the radius. Thus, you can substitute it into the equation and solve for "A".
A = πr²
A = π(10)²
A = π x (100)
A = 314.2 in²
For 15.), you have been given the diameter. To find the radius, you need to divide this value by 2. Once you find the radius, you can plug it into the equation and simplify like above.
diameter = 15.2 ft
radius = 7.6 ft
A = πr²
A = π(7.6)²
A = π x (57.76)
A = 181.5 ft²
A. 7/4 is a rational number but not a whole number.
To find the answer find out how many cubes there are altogether. 27 student with 5 cubes each = 135.
Take away 135 from the 189 , and you'll get the rest left that are spinners, which is 54.
54/27= 2 so
There are 2 spinners for each student.
Hope it can give u some help
Answer:
because there's an equals sign and if you want the answer x=1
Step-by-step explanation:
because 9=3x+6 cancel out 6, 3=3x divided on both sides, 1=x
