d = 0.733....
Answer:
3.00
Step-by-step explanation:
let us look at triangle BAD first. Since it give us a complete information. using the formula
sin 0 = opposite / hypotenuse
sin 0 = 2.8/5.5
sin 0 =0.5091
transfer the sin to the other side
angle 0 = 30.6 ° (angle BAD)
it is given angle DAC = angle BAD
so angle DAC also =30.6°
since CD is an opposite than we use the previous formula back
sin 0 = opposite / hypotenuse
sin 30.6 = CD / 5.8
CD = 2.95 or 3.00
So we want to know the volume of a sphere in terms of pi if we know the area of the sphere is equal to A=9pi. So the area of the sphere is A=4*pi*r^2 and the volume V=(4/3)*pi*r^3. We can get the radius from the area: 9pi=4*pi*r^2 and we see the pi cancels out: 9=4*r^2. We divide by 4 and take the square root: r=sqrt(9/4)=3/2. So r=3/2 and we can input it into volume V.
V=(4/3)*(3/2)^3*pi=(4/3)*(27/8)*pi=(9/4)*pi.
So the volume of the sphere is V=(9/4)*pi cubic feet.
One dozen = 12
3 dozens = 12*3 or 36
To make 36 cookies you need 4 eggs and 1/2cups of chocolate chips.
Ben wants to make 12 dozen or 144 cookies.
144/36 = 4
To find out how many chocolate chips and eggs he needs we can multiply the amount of chocolate chips and eggs it takes to make 3 dozen by 4 to find out how many chocolate chips and eggs he needs to make 12 dozen.
4 *4= 16 He will need 16 eggs
4*1/2= 2 He will need 2 Cups of chocolate chips.
