Answer:
a) The height of the image = 11.2 millimeters
b) The distance between the camera and her friend = 2.24 meters
Step-by-step explanation:
<u>Part A: find the height of the image:</u>
distance from the lens to the film = 24 millimeters
distance from the lens to the her friend = 3 meters = 3000 millimeters
height of her friend = 140 centimeters = 1400 mm
the height of the image = x
Using the similarity :

<u>Part B: find the distance between the camera and her friend</u>
If the height of the image on the film of her friend is 15 millimeters.
Let the the distance between the camera and her friend = y

Suface area= 2πrh+2πr²
= 2×3.14×2×15+2×3.14×2²
= 6.28×2×15+6.28×4
=188.4+25.12
=213.52
so Surface area=213.52cm
1/3 because if you dived 7 by both of them by you would get 1/3
Answer:
Option 3
Step-by-step explanation:
Using the order of operations, you will find out that 7 x 10^3 = 7,000, and 3 x 10^2 = 300. Dividing 7,000 by 300 will get you 23.333~, so 300 does go into 7,000 a little more than 20 times.
