the cylindrical part of an architectural column has a height of 305 cm and a diameter of 30 cm find the volume of the cylindrical part of the column. use 3.14 for pi and round youre answer to the nearest cubic centimete if needed.

Step-by-step explanation:

Given:

Radius(r)= 25 cm = 25/100= 0.25 m

[1 cm = 1/100m]

Height (h)= 3.5 m

Curved surface area of Cylinder= 2πrh

= 2× (22/7) × 0.25 × 3.5

= 2× 22× 0.25 × 0.5

= 2× 0.5 ×22× 0.25

= 1 ×22× 0.25

= 5.5 m²

Curved surface area of 1 Cylindrical column= 5.5 m²

Curved surface area of 10 Cylindrical column= 5.5 × 10= 55 m²

Rate for painting 1 m² of the cylindrical column = ₹ 15.50

Cost of painting 10 cylindrical columns= 55 × 15.50 = ₹ 852.5.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

step-by-step explanation:

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
