Question

Please answer this questionn!

Answer 1

Answer:

Step-by-step explanation:

Curved surface area of cone = π r l

Here r (radius) = 2.5 cm

Since radius is half of Diameter.

l = slant height

from right angle triangle as mentioned in the diagram ,l is hypotenuse,it can be calculated by Pythagoras theorem.

A.T.Q conical part is to painted orange ,So orange colour is required to paint CURVED SURFACE AREA of cone

=

The part if the rocket to be painted yellow,is the CSA of cylindrical shape = 2πrh

here h (height) = 20 cm

Radius (r) = 1.5 cm

Orange paint to be painted on 51.05 sq-cm area,

Yellow paint to be painted on 188.49 sq-cm area.

Hope it helps you.
