Answer:
63
Step-by-step explanation:
the first one is 9x bigger then the second one
so 7x9 is 63
Area = r^2 x PI
to find r take the square root of the area:
r = √100 = 10
The circumference of a circle is the diameter times PI.
The diameter is 2 times r = 2 x 10 = 20
The circumference = 20PI m
The answer is C.
Answer:
12 ft
Step-by-step explanation:
P=2L+2w
56=2(w+4)+2w
56=2w+8+2w
56=4w+8
4w=48
w=12
there are the ways to reach that are conduction,convection and radiation
