Where:
d: It is the diameter of the circle
They tell us that:

Substituting:

Answer:
Option B
Answer:
28 minutes
3.5 x 8 = 28
Step-by-step explanation:
Feeding the whole school (8/8) would take 8 times as long as feeding 1/8 of the school.
3 1/2 can become 3.5 if that's easier for you to work with.
Feeding 1/8 of the school is 3.5 x 1 = 3.5
Feeding 2/8 of the school is 3.5 x 2 = 7
Feeding 8/8 of the school is 3.5 x 8 = 28
It takes 28 minutes to feed the whole school (8/8)
So a times 10^n where 1≤|a|<10 and n is an integer is what i learned
so
a.
234=
2.34 times 100=
2.34 times 10²
b.
0.000052=
5.2 times 1/100000=
5.2 times 10⁻⁵
c.
-220000=
-2.2 times 100000=
-2.2 times 10⁵
d. ok, so just count the spaces moved to the left
-18.2 times 10⁻¹⁵
