Answer:
6.5cm
Step-by-step explanation:
please find attached the question
the length of the apothem can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base = 9.4/2 = 4.7cm
c = hypotenuse = 8cm
a² + 4.7² = 8²
a² + 22.09 = 64
a² = 41.91
find the square root
a = 6.5 cm
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
