is3nk 1.a) sudut POB = 90/2 = 45
OP = OB cos sudut POB
$OP = 20 cos 45$
$OP = 20 . \frac{1}{2} \sqrt{2}$
$OP = 10 \sqrt{2}$

1.b) luas tembereng = luas juring AOB - segitiga AOB
luas tembereng = $\frac{90}{360} \pi r^{2}- \frac{1}{2}at$
dimana, r = a = t = OB = 20
maka,
luas tembereng = $\frac{1}{4}. 3,14. 20^{2} - \frac{1}{2}.20.20$
luas tembereng = 314 - 200
luas tembereng = 114

2.a) tali busur QR = 60/360 keliling lingkaran
= $\frac{1}{6} \pi d$
= $\frac{1}{6} .3,14.20$
=10,467

2.b) PT = PR cos 60/2
= 10 cos 30
= $10. \frac{1}{2} \sqrt{3}$
= $5 \sqrt{3}$

2.c) luas tembereng = $\frac{60}{360}. \pi . PR^{2} - \frac{1}{2}.QR.PT$
luas tembereng = $\frac{1}{6}. 3,14. PR^{2} - \frac{1}{2}.(2.PR.cos60).PT$
luas tembereng = $\frac{1}{6}. 3,14.10^{2} - \frac{1}{2}.(2.10.\frac{1}{2}).5 \sqrt{3}$
luas tembereng = $\frac{1}{6}. 314 - \frac{1}{2}.10.5 \sqrt{3}$
luas tembereng = $\frac{314}{6} - 25 \sqrt{3}$
