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}

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

x^2=4^2+4^2

x^2=16+16

x^2=32

We take positive square root to obtain

x=\sqrt{32}

x=4\sqrt{2}

x=5.66ft

Rounding to the nearest feet we have x=6ft

By what number should-15/56 be divided to get -5/6<br><br>pls pls pls pls I need your help ​
mr_godi [17]

Answer:

The desired divisor is n = 21

Step-by-step explanation:

Let that number be n.  Then:

-15/56        -5

---------- = ---------

     n            6

Through cross-multiplication we get:

(-15/56)*6 = -5n, which reduces to:

(-15)(7) = -5n, or 3(7) = n

The desired divisor is n = 21
