Surface area of cone is a sum of surface of its base and surface of its mantle.
Surface of its base is a circle which surface we will calculate like this:
Sb = pi*r^2 where r is d/2
Sb = 201m^2
Surface of mantle we calculate by:
Sm = pi*l*r where l is length of side of cone.
l =

= 25.3
Sm = 635.8m^2
Total suface is:
Sb + Sm = 836.8m^2
Answer:
this is an example
Step-by-step explanation:
Answer:
800 grams = 1.76 pounds
700 grams = 1.54 pounds
also to give brainiest, two people need to answer and when two people answer you click the brain the top right corner i believe and pick which answer is better.
Step-by-step explanation:
Essentially, we need to know what are 800 grams in pounds-
(1 pound =453.592
x= 800)
we have to divide 800 by 453.592, and the result is 1.763699... rounding it: 1.76
now we do the same for 700 :
700 divided by 453.592 is 1.5432... so rounding it down: 1.54
Answer:
2 visits
Step-by-step explanation:
Step one:
cost for membership=$27
cost per visit= $1
let the number of visit be x
the total is expressed as
y=mx+c
total =x+27
Step two:
given a total of $29
the number of visits can be found as
29=x+27
29-27=x
x=2
The signs of two products with opposite numbers would be negative-
