What is the area of a circle with diameter = 12yd, using 3.14 for ? thx :)

37.68yd

Step-by-step explanation:

a=πr² or a=πd

a=3.14•12=37.68

113.04yd²

Step-by-step explanation:

Area of a circle equation: A = πr²

Radius is 1/2 the diameter

(3.14)(6)²

You need to square 6 before multiplying it all together. Then you get your answer of 113.04 :) hope this helped

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
