Diameter:13 in

r=13/2=6.5 in

Aria of the whole cookie cake:r*r*pi = 6.5*6.5*3.14=132.665 and then you divide it by 4 and you get 33.18

So, the answer is C:33.18

Cookie Cake is in the form of a circle.

Radius of circle = 1/2 * diameter of circle = 1/2*13=13/2=6.5 in

Thus the Area of the circle = \pi r^2

= \pi *6.5^2

= 132.73

Area of a fourth of the Cookie cake = \frac{1}{4} *132.73 = 33.18 in^2

The radius of a circle is 7 cm what is the cirfufance​
OlgaM077 [116]

Answer:

44 cm

Step-by-step explanation:

The circumference (C) of a circle is calculated using the formula

C = 2πr ← where r is the radius

here r = 7, hence

C = 2 ×π × 7 = 14π ≈ 44 cm ( to nearest whole number )

If an intravenous fluid is adjusted to deliver 15 mg of medication to a patient per hour, how many milligrams of medication are
adelina 88 [10]

Answer: 0.125 mg per half minute

Step-by-step explanation:

15mg per hour can be written as 15mg/h

To find out how many mg of medication are delivered per half minute you can convert from hour to minutes

There are 60 minutes in 1 hour, so you can use the conversion factor (1h/60 min) and multiply the expression by it

15 mg/h (1h/60min) = 0.25 mg/min

But the question is per half minute so you have to multiply and divide the previous expression by 0.5 (To obtain 0.5 min in the denominator, which is half minute)

Then,

(0.25 mg/min ) (0.5/0.5) = 0.125 mg/ 0.5 min (0.125 mg per half minute)
