Answer:

Mrs. Stewart paid $86.25 for all the books.

Step-by-step explanation:

With the information provided, you have to add the result of multiplying the nine books for its price plus the remaining books for the price per book. To find the number of the remaining books you can substract the nine books from the total amount Mrs. Stewart purchased.

Cost=(9*4.95)+((15-9)*6.95)

Cost=44.55+41.7

Cost=86.25

According to this, the answer is that Mrs. Stewart paid $86.25 for all the books.

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

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}
