Question

Tolong yaa buat besok

Answer 1

4.a.Kel=(1/6x(22/7x84))+42+42
=(1/6x264)+84
=44+84
= 128 cm
Luas=(1/6x(22/7x42x42)
=(1/6x(5544))
=924cm2
b.Kel=(1/4x(3.14x24))+(1/4x(3.14x36))+12
=(1/4x(75.36))+(1/4x(113.04))+12
=18,84+28,26+12
=59,10cm
Luas=(1/4x(3.14x18x18))-(1/4x(3.14x12x12))
=(1/4x(1017,36))-(1/4x(452.16))
=(254.34)-(113.04)
=141,3cm2
Maaf Klo salah(Kurang Teliti)
