A converging lens of focal length 5 cm is placed at a distance of 20
lesya [120]

The object should be placed 20/cm from the lens so as to form its real image on the screen

<h3>Mirror equation</h3>

The mirror equation is given according to the expression below;

1/f = 1/u + 1/v

where

f is the focal length

u is the object distance

v is the image distance

Given the following parameters

f = 5cm

v = 20cm

Required

object distance u

Substitute

1/5 = 1/u +1/20

1/u = 1/5-1/20
1/u = 3/20

u = 20/3 cm

Hence the object should be placed 20/cm from the lens so as to form its real image on the screen

Find the volume of the cone shown below.
BlackZzzverrR [31]

Answer:

D

Step-by-step explanation:

The formula for volume of cone is  V=\frac{1}{3}\pi r^2 h

Where

V is the volume

r is the radius of the circular base

h is the height of the cone

<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>

<em>V=\frac{1}{3}\pi (9)^2(12)\\=324 \pi</em>

<em />

<em>correct answer is D</em>
