A regular hexagon has sides of 3 feet. What is the area of the hexagon?
Dominik [7]

Answer:

13.5√(3) ft^2

Step-by-step explanation:

In this, question, we are to calculate the area of the hexagon

Mathematically, we can calculate the area of a hexagon using the formula;

A = {3√(3)/2}a^2

where a is the length of the side which is 3 feet

substituting the value of 3 into the formula, we have;

A = 3√3/2 * 3^2 = 27 √(3)/2 = 13.5√(3) ft^2

Which choice is more than 11 but less than 12?
kumpel [21]
Let
x--------> the number

we know that
11²=121
12²=144

then
x² must be greater than 121  and less than 144

case a) <span>√115
if x=</span><span>√115
then
 x</span>²=115-------> is not greater than 121

case b) <span>√121 
</span>if x=√121
then
 x²=121-------> is not greater than 121

case c) <span>√136
</span>if x=√136
then
 x²=136-------> is greater than 121 and is less than 144------> is ok

case d) <span>√150
</span>if x=√150
then
 x²=150------> is not less than 144

therefore

the answer is
√136

What's absolute value |-8|
maks197457 [2]
The absolute value of a number can never be negative. That's because it represents the distance of a number from zero on a number line. The number -8 is 8 digits to the left of zero on a number line. So, the absolute value of -8 would be 8 .

Let me know if you have any questions regarding this problem!
Thanks!
