17. Perpendicular height ofcone is 12 om and its slanheight is 13 cm. Find the radiusof the base of the cone​

Answer»

ANSWER:

Step-by-step explanation:

Given for the cone,

Perpendicular HEIGHT [h]= 12 cm

Slant height [l]=13 cm

Therefore,

r²= l² - h²

=> r²= 13² -12²

=> r =√169-144

=> r = √25

=> r= 5CM
