Question

thr radius and slant height of ice cream cone is 18cm and 20cm respectively.find its CSA and TSA​

Answer 1

Answer:

given r = 18 cm , L = 20 cm

to find CSA and TSA

CSA = π r L

=> 22/7 × 18 × 20

=> 1131.4 sq cm

TSA = CSA + πr2

=> 1131.4 + 22/7×18×18

=> 1131.4 + 1018.3

=> 2149.7 sq cm

Answer 2

Answer:

R=18

L=20

Step-by-step explanation:

$tsa = \pi \: r \: l \: + \pi \: {r}^{2} \\ \\ so \: tsa = \pi(18)(18 + 20) \\ \\ \\ \\ csa = \pi \: r \: l \\ = \pi(18)(20)$
