Answer:
9.8cm
Step-by-step explanation:
From the above diagram, the following were obtained:
Height = 9cm
Diameter = 8cm
Radius = d /2 = 8/ 2 = 4cm
Let the slant height = y
Using pythagoras theorem, we can obtain the value of y as follows:
y^2 = h^2 + r^2
y^2 = 9^2 + 4^2
y^2 = 81 + 16
y^2 = 97
Take the square root of both side
y =√97
y = 9.8cm
