Answer:
C = 6.28
A = 3.14
Step-by-step explanation:
use the equations for area and circumference to solve
C = pi d
A = pi r^2
I like to remember these using the saying Cherry pie's delicious, Apple pie's are too so Cherry = pi's delicious, Apple = pi's r 2
so with the diameter of 2 plug in to get circumference
C = 3.14 (2)
C = 6.28
and the equation for area uses radius not diameter but we know that d/2=r so radius is 1, plug in to solve
A = 3.14 (1)^2
A = 3.14 (1)
A = 3.14
Hope this helps! :)
Answer:
.
Step-by-step explanation:
It is given that a and 46° are complementary angles.
It is given that a and b are supplementary angles.
Angle conjugate to c is 283°.
Sum of all angles at a point is 360 degrees.
Therefore, .
<em>Jen bought 5 CDs for $57.50. What was the unit rate?</em>
The given price for five CD's is $57.50. You're being asked to find the unit rate, also known as unit price, which is the cost of one CD.
To find the unit rate of an item, you need to divide the price by the quantity.
The first step is to substitute the given amounts into the above formula.
Now, all you need to do is divide.
The unit rate is $11.50 per CD.
Answer:
36
Step-by-step explanation:
for the equation, we have to add 1 cubed, 2 cubed and 3 cubed together to get the answer. That equation would look like this
1^3 + 2^3 + 3^3
or expanded out
(1x1x1)+(2x2x2)+(3x3x3)
Solving that down, the equation turns into this
1 + 8 + 27
Adding those values together leaves us with 36!
Hope this helped, have a good rest of your day!
3097 is the value you get when rounded off to nearest whole number
