Answer:
D 111.4 cm²
Step-by-step explanation:
Answer:
0 and yes
Step-by-step explanation:
Let a=6m where m is any integer since a is divisible by 6. (a+12)/3=(6m+12)/3=2m+4 which is also an integer. The remainder is 0.
Since n is divisible by 3, n can be written as 3a, where a is any integer and m can be written as 2b, where b is any integer. n*m+12=6ab+12 which is divisible by 2.
Answer:
Total Area = 236.715 sq ft
Step-by-step explanation:
this is a composite figure made up of a circle and a rectangle; find the area of each and then add them together
A(circle) = πr²
= π(7.5²)
= 176.715
A(rectangle) = 15(4) which is 60
Total Area = 236.715 sq ft
