Question

Math reeeeeeeeeeeeee

Answer 1

9.8cm

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
