5 0

------------------------------------
Formula
------------------------------------
Area = πr²

------------------------------------
Find Radius
------------------------------------
Diameter = 2 ft
Radius = Diameter ÷ 2
Radius = 2 ÷ 2
Radius = 1 ft

------------------------------------
Area of the manhole
------------------------------------
Area = πr²
Area = (3.14)(1)²
Area = 3.14 ft²

------------------------------------
Answer: 3.14 ft²

Let the reduced price be x

If he paid for 6 rounds, he paid 1 round at full price of $19 and 5 rounds at reduced price:
19 + 5x = 59
5x = 59 - 19
5x = 40
x = 40 ÷ 5
x = 8

The reduced price is at $8 per round.

Suppose two angles are supplementary and one of them measures 31 degress what is the measure of the other angle

Nady [450]

Supplementary means it adds up to 180 degrees.
So if one side is 31 degrees, you would need to subtract that from 180 to find the other side.
-----------------------
180 - 31 = 149
-----------------------
The other angle would be 149 degrees.
