10. hitunglah keliling daerah yang diarsir pada gambar berikutdibantu kak yang c aja makasihh, jangan ngasal yaa please​

Jawaban soal A
kliling = d + (1/2 x π x d)
= 7 + ( 1/2 x 22/7 x 7)
= 7 + 11
= 18 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal B
kliling = ( 1/2 x π x d) + ( π x d)
= ( 1/2 x 22/7 x 14) + ( 22/7 x 7)
= ( 11 x 2) + 22
= 22 + 22
= 44 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal C
kliling = 2 x ( π x d )
= 2 x 22/7 x 14
= 44 x 2
= 88 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal D
kliling = 2(p) + ( π x d)
= 2 (10) + ( 22/7 x 7)
= 20 + 22
= 42 cm
─────── ೄྀ࿐ ˊˎ-


jawabn soal E
kliling = (1/2 x π x d) + ( π x d)
= ( 1/2 x 3,14 x 10) + ( 3,14 x 5)
= 15,7 + 15,7
= 31,4 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal F
kliling = π x d
= 22/7 x 7
= 22 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal G
kliling = π x d
= 22/7 x 7
= 22 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal H
kliling = (1/2 x 2 x π x r) + ( 1/2 x 2 x π x r)
= (22/7 x 14) + (22/7 x 7)
= 44 + 22
= 66 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal i
d = 1/2 x 10
= 5
kliling = 2 x π x d
= 2 x 3,14 x 5
= 31,4 cm
─────── ೄྀ࿐ ˊˎ-


jawaban soal j
d = 1/2 x 14
= 7
kliling = 2 x π x d
= 2 x 22/7 x 7
= 44 cm
─────── ೄྀ࿐ ˊˎ-
