tolong isiin pliss saya gak tau cranya ? pliss donkk isiin pke cara nya soalnya besok mau d kumpulin!

a. lsk = πrs
= 3,14.6.10
= 18,84.10
= 188,40
b. lpk = πr(r+s)
= 3,14.6(6+10)
= 18,84.16
= 301,44
c. v = 1/3.πr²t
= 1/3.3,14.6.6.8
= 628.48
= 301,44
cara mencari s = r²+t²=s²
6²+8²=s²
36+64= 100
s²=100
s= 10

A)Dik:t = 8 cm persegi
=r=6 cm persegi
s^2=√6^2+8^2
=36+64
=√100=10 cm persegi
jdi s = 10 cm persegi
Dit:Luas selimut krct?
=πrs=3,14×6×10
=188,4 cm persegi

B)Dik: (sama seperti yg diatas)
Dit:Luas permuakaan kerucut?
jwb:πr(r+s)
=3,14×6(6+10)
=18,84(16)
=301,44 cm persegi

C)volume:1/3πr^2t
=1/3×3,14×6×6×8(1/3 dicoret dgn angka 6)
=3,14×2×6×8
=6,28×48
=301,44 cm kubik
