Given:

The block is in the shape of a cylinder.

Radius of the block (r) = 3 cm

Length of the block (h) = 10 cm

2.9 gram = 1 cubic centimeter

To find:

The weight of the cylindrical block.

Solution:

The value of π = 3.142

Volume of the cylindrical block =

Volume of the cylindrical block = 282.7 cubic centimeter

To convert cubic centimeter into grams:

1 cubic centimeter = 2.9 grams

282.7 cubic centimeter = 282.7 × 2.9

                                       = 819.83 grams

The weight of the cylindrical block is 819.83 grams.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
