Answer:
15.7 cm
Step-by-step explanation:
Circumference= Diameter * Pi
Hence,
Circumference of the circle= 3.14 * 5
=15.7 cm
Answer:
C
Step-by-step explanation:
SA=pi*r^2+pi*r*s
SA=3.14*3^2+3.14*3*8
SA=3.14*9+3.14*24
SA=103.62
SA= about 104 inches
Aubrey included the base (you can't put on a hat that has a bottom), the right work should be:
SAhat=pi*r*s
SAhat=3.14*3*8
SAhat=3.14*24
SAhat=75.36
SAhat= about 75
Thus, answer is C
Our equation for the area of a rectangle is l x w = A (length times width equals area)
We know that l=w+20 so we can plug this into our equation.
It is now, (w+20) x w =800
We can then solve for w
w^2 +20w =800
We can subtract 800 on each side to get
w^2 +20w - 800 =0
We then factor to get
(w-20)(w+40)=0
This gives us w =20 and w = -40
Width cannot be negative so our width will be 20 feet
Since our length is 20 more than this, then our length will be 40feet
So the dimensions of the rectangle are 20 ft wide by 40 ft long
Answer:
There isn't any picture, so I'm assuming that the volume is l*w*h. Just multiply the three dimensions.
