πr2h. the volume of a cone is 300 cm3 and the height of the cone is 10 cm. what is the approximate radius of the cone?
a) 3 cm
b) 5 cm
c) 9 cm
d) 28 cm

 The correct option is

(B) 5.35 cm.

Step-by-step explanation:  Given that the formula for the volume of a cone with radius r units and height h units is

Also, given that the volume of a cone is 300 cm³ and the height of the cone is 10 cm.

We are to find the approximate radius of the cone.

From the given formula, we can write

Since the radius of the cone cannot be negative, so r = 5 am.

Thus, the required approximate radius of the cone is 5 cm.

Option (B) is CORRECT.

Option B) 5 cm

Step-by-step explanation:

We are given the following information in question:

Volume of cone =

The volume of a cone is 300 cm cube and the height of the cone is 10 cm.

Putting the values in above equation:

Hence, the approximate radius of the cone is 5 cm.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
