The circumference of every circle is (pi) times (diameter).
The diameter is (2 x radius), so we can write
Circumference = (pi) x (2 x radius) .
The question gives us the circumference, and the number to use for (pi).
I shall now pluggum in:
(31.4 cm) = (3.14) x (2 x radius)
Divide each side by 3.14: (31.4 cm)/(3.14) = 2 x radius
Divide each side by 2 : (31.4 cm) / (2 x 3.14) = radius
5 cm = radius
Well it would be 39 because 39 ÷ 39 would be 1, and you should be able to divide 250 by 39 too! Hope that helped!
Answer:
P = - 15
Step-by-step explanation:
P+7-5 = -10 - 3
P +2 = - 13
(If taking from one side,you must do to the other to get P alone.)
P+2 = - 13
-2 = - 2
The positive 2, minus the negative 2 cancels each other out, now we must subtract 2 from our other side. - 13 - 2 = - 15
P = -15
<em>Answer:</em>
<em> 56 tablets</em>
<em>Step-by-step explanation:</em>
Jonah knows that Mr. Robinson needs 14 tablets for a week's supply of an anti-inflammatory drug.
<em>Mr. Robinson is going on vacation and needs a 4-week supply. </em>
<em>So </em><u><em>multiplying 4 with the weekly supply</em></u><em> will yield the required result. </em>
So, number of tablets Jonia needs to fill is,
=4\times 14
=56
<em>Therefore, Jonah needs </em><u><em>56 tablets</em></u><em> in order to fill his prescription</em>
