Find the circumference and the area of a circle with diameter . Use the value 3.14 for (pi sign) , and do not round your answers. Be sure to include the correct units in
@johnweldon1993
\[\large \text{Area} = \pi r^2\] \[\large \text{Circumference} = 2 \pi r\] \[\large \text{Radius} = \frac{\text{Diameter}}{2}\]
so....
so.... post a diameter...
The diameter is 8
Alright...So now with all those formulas.. \[\large \text{Radius} = \frac{8}{2}\] \[\large \text{Radius} = 4\] Now that you know that...plug that...and the fact that pi 3.14 into the equation I have posted above \[\large \text{Circumference} = 2(3.14)(4) = ?\] \[\large \text{Area} = (3.14)(4)^2 = ?\]
dont uderstand
What don't you understand? To solve for the circumference you would do 2 times 3.14 times 4 And to solve for the area you do 3.14 times 4 squared
im stupid so... i still dont uderstand wat u r saying
sorry
