Find Radius
--------------------------------------
Radius = Diameter ÷ 2
Radius = 18 ÷ 2
Radius = 9 inches
--------------------------------------
Area of the Pizza
--------------------------------------
Area = πr²
Area = π x (9)²
Area = 81π
Area = 254.47 in² (nearest hundredth)
--------------------------------------
find area of 1 slice of pizza
--------------------------------------
10 slices = 254.47 in²
1 slice = 254.47 ÷ 10
1 slice = 25.44 in²
--------------------------------------
Find area of 3 slices of pizza
--------------------------------------
1 slice = 25.44 in²
3 slices = 25.44 x 3
3 slices = 766.32 in²
--------------------------------------
Answer: 766.32 in²
--------------------------------------
Answer: x = 7
Step-by-step explanation:
do opposites to both sides. what is the opposite of -5? it would be plus 5.
add 5 to both sides
3x = 21
now what is the opposite of 3 times x? 3 divided by.
divide 3 to both sides
x = 7
3 feet is 36 inches.
36 x 4 is 144.
There are 144 1/4 inch pieces in 3ft of fishing line.
Given the equation:
Applying the exponent laws:
![\begin{gathered} \sqrt[3]{((5x-16)^3-4)^3}=\sqrt[3]{216000} \\ (5x-16)^3-4=60 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csqrt%5B3%5D%7B%28%285x-16%29%5E3-4%29%5E3%7D%3D%5Csqrt%5B3%5D%7B216000%7D%20%5C%5C%20%285x-16%29%5E3-4%3D60%20%5Cend%7Bgathered%7D)

Answer: x = 4
Answer:
I am not sure if I understand the question correctly, but I believe it would be 1 hundred in each group.
Step-by-step explanation:
400 divided by 4 = 100
