Answer:
If the diameter is 18 then the radius r=9 so the area is:
πr2=81π≅254.469
Step-by-step explanation:
Explanation:
The area of a circle is given by the formula πr2 where r is the radius.
I can't speak to the cactus specifically, but any sphere has a surface area of
and a volume of
, so the area-to-volume ratio wold be
Where <em>r</em> is the radius of the sphere.
Answer:
80
Step-by-step explanation:
Angles on a straight line sum to 180
65+35=100
180-100=80
angle r=80
Answer:
a constant is a data item whose value cannot change during the program execution just as its name implies that the value is constant a variable is a data item whose value can change during the program's execution . Thus as its name implies the the value can vary
