Answer:
D. 8
Step-by-step explanation:
C= 2πr
π= 3.14
C= 25.12
25.12 = 2 * 3.14 * r
r= 4
d= 2r
d= 8
A=bh/2, that is area is equal to half of the product of the base and height, so in this case:
A=(1/2)*10*24
Yes that is a parallelogram
Check the picture below, keeping in mind that opposides sides and interior angles in a parallelogram are congruent.
Set up a proportion.
pounds / milligrams of medicine
195/279 = 130/x
195x = 279 times 130
195x =36,270
x = 36,270/195
x = 186
A patient weighing 130 pounds needs 186 milligrams of medicine.
