Свойство хорды окружности: Радиус (а значит и диаметр), перпендикулярный хорде, делит эту хорду пополам.Отсюда следует, что СМ=ДМ=18/2=9 см

Read, translate and render the dialogues in indirect speech.
A.
- What's the matter with your arm, Ann? Why is it in a sling?
- I was careless while boiling the milk this morning and scalded it. I didn't know what to do, so I ran to the polyclinic, and the nurse there put some ointment on it and bandaged it. It is much better now, and I think it won't blister.
B.
- Why are you limping, John? What is the matter?
- I was playing football yesterday and sprained my ankle. It hurts badly. I can hardly walk, as you see.
- You mustn't walk at all. Lie down and put a compress on your ankle. That's the best remedy. Call the doctor and he will give you a sick-leave for a few days.
C.
- What is the matter with you, my boy?
- Something is wrong with my knee. It hurts.
- Let me have a look at it... It's a splinter. You have come just in time to avoid an infection and an abscess.
3. Dialogue between a Mother (M), her Son (S) and the Doctor (D).
M: Your nose is clogged up, your voice is hoarse and your face flushed. You must have a cold. I'm sure. I hope it's nothing more. Where did you manage to get it?
S: I don't know myself. I must have caught cold last night after a game of football when I felt so hot that I even took my jacket off.
M: How thoughtless (careless) of you, the evening was chilly and windy. Now you'll have to stay in. Here's the thermometer, take your temperature.
S: Oh, I'll be all right in a few hours.
M: Now, you do what you are told. Put the thermometer under your arm (in the armpit)... Oh, it's thirty eight point three. You'll have to stay away from classes today. I'll call the doctor (I'll have the doctor in). (She phones to the local out-patient hospital and is told that the doctor will call while making his daily round of the district).
D: What do you complain of, my boy?
S: I have a bad (splitting) headache and a sore throat. I feel sort of feverish.
D: Let me feel your pulse. Open your mouth, please. I see your tongue is coated and your throat inflamed. Now, strip to the waist, please. (The doctor sounds the boy's lungs.) Take a deep breath... (To the mother.) Your son is to keep his bed for three days. Here is the prescription. The medicine is to be taken three times a day before meals, two tablespoonfuls each time. It will help to keep the fever down. (To the son.) Blow your nose gently, young man, or else you'll have an earache... Nothing serious, but don't get up before Wednesday, as there might be complications (bad after-effects).
