Question

Can someone help me to find TSA of this figure?​

Answer 1

is approximately 100 cm ²

Step -by-step explanation

`r \: = 10 \\ l \: = 21.81 \\ T.S.A \: o</strong><strong>f</strong><strong> </strong><strong>a</strong><strong> \: cone\: = \pi * r(r + l)`

`(22)/(7) * 10(10 + 21.81) \\ (22)/(7) * 10(31.81) \\ (22)/(7) * 318.1`

`(22)/(7) * 318.1 \\ = 999.7 \\ = 100 {cm}^(2)`
