Step-by-step explanation:

Given:-

In a Cylinder

Height=15cm

volume=600 cm^3

To find:-

The area of the vase circle in the Cylinder

Solution:-

Let radius=r

As we know that in a Cylinder

Substitute the values

Now interchange both sides and get r

Now The base of Cylinder is a circle

where r=5.1cm

as we know that in a Circle

Substitute the values

Answer 2

Answer:

Solution:

Let radius=r

As we know that in a Cylinder

Volume Tr²h

Substitute the values

: 600: 22 7 x 15² x h

: →600: = 22 7 x r² x 15

• Now interchange both sides and get

: → p2 600 × 7 22 × 15

280 22 : =

: → r² = 26.36

.. → r= √26.36

: → r= 5.1cm

• Now The base of Cylinder is a circle

• where r-5.1cm

as we know that in a Circle

Area - r²

• Substitute the values

: →→ Area 22 7 = x 5.1²

→ Area: = 22 7 × 26.3

: → Area: = 22 × 263 7 x 10

: Area = 8265.7cm²
