Question

I WILL GIVE YOU BRAINLY PLSS Worth 19 points

Answer 1

Answer:

942

Step-by-step explanation :

so your d is 300 so your r = 300/2= 150  

a=3.14*r*r= 3.14*150*150= 70650

c= 3.14*d= 3.14*300= 942

OR

The curved surface area of solid cylinder is  

 

As we are given that:

Diameter of solid cylinder = 8 cm

Length or Height o solid cylinder = 140 cm

Formula used to calculate the curved surface area of cylinder is:2n x h

Curved surface area of cylinder =2r x h  

where,

r = radius of cylinder

h = height or length of cylinder

Radius of cylinder =  daimeter

Now putting all the given values in above formula, we get:

Curved surface area of cylinder =  2x 22/7 x 140cm

Curved surface area of cylinder = $3520cm^{2}$

Therefore, the curved surface area of solid cylinder is3520cm^{2}
