-3+11p
first you add 1+2p that gets you -3 then you do 9p-4 and you get 11p from there you can either solve it, or leave it as is, depending on what your teacher wants.
You would use the volume of a cone formula ((1/3)(pi)(r^2)h) so it would be (1/3)(pi)(7^2)(24). That simplified to 392(pi) units^3. So the answer is c
Solution:
we have given the length of the rectangular card-
and, width-
now, the area of the card will be- length×width.
so, we have-
we also have given the length of ribbon-
and, width-
so, area of the ribbon is-
length×width
now the area of shaded gray region will be-
Hence, the required expression would the above expression.
Hi,
Since the perimeter of a rectangle is equal to twice the length plus twice the width, what you want to do here is P = 2(8) + 2(x) = 16 + 2x
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
