Answer:
2,294.66 square inches
Step-by-step explanation:
The area of an octagon is given by the formula:
A = 2 * a² * ( 1 + √2 )
So, if we input the numbers we have:
A = 2 * 21.8² * ( 1 + √2 )
A = 2 * 475.24 * (2.4142)
A = 2,294.66 square inches
As you can see, if you double the side of an octagon, its area will quadruples, which is logic since the one variable in the calculation of the area is the side's length... that is squared. So, if you double it, that double factor is squared.
It's as if we had written
A = 2 * (10.9 * 2)² * ( 1 + √2 )
A = 2 * (10.9² * 2²) * ( 1 + √2 )
Answer:12
Step-by-step explanation:
Given
Balthazar,Rudy,Jebediah and Ezekiel in a single-File line to pull sleigh
Jebediah and Ezekiel Stay together
i.e. we need to arrange three person considering Ezekiel and jebediah as Single person
therefore 3 person can be arrange in 3! ways =6
and also Ezekiel and Jebediah can be arranged in 2 ways
Therefore a total of ways are possible

Amount of pizza eaten by Charlie.
7/6× 22/7 × (101/2)² =9350.91667
Amount of pizza eaten by Julie
5/12 × 22/7 × 90.5² = 10725.3273
Answer = Julie

Answer:
y = 1/3x+6
Step-by-step explanation:
y = -3x+2 is in slope intercept form y = mx+b where m is the slope and b is the y intercept
The slope is -3
Perpendicular lines have slopes that are negative reciprocals
The slope of the perpendicular line is -1/-3 = 1/3
The equation of the new line is
y = 1/3x +b
Using the point that passes through the line ( 6,8) and substituting in for x and y
8 = 1/3(6) +b
8 = 2+b
8-2 =b
6 =b
The equation becomes
y = 1/3x+6
