q1 a cone has a base radius of 5cm and height of 12cm(a)calculate it slant height (b)calculate it total surface area,leave answer in terms of it

Answer 1

base radius = r = 5 cm
cone height = h = 12 cm
Use Pythagoras theorem to find slant height
slant height, L = sqrt(5²+12²)
=sqrt(169)=13 cm

Total surface area
= π r²+πrL

Substitute numerical values to get numerical answer.

Answer 2

pls help me out,dis is my first time

Answer 3

13cm

Answer 4

Pleasea help me out am stock

Answer 5

YES

Answer 6

Using pythagoras rule
L^2/l square. 5^2 + 12^2.
25+144=169.
L=square of 169=13
Slant 13cm
