Answer:
- circumference: 62.8 ft
- area: 314 ft²
Step-by-step explanation:
The circumference is given by the formula ...
C = πd
Using the given numbers, the circumference is ...
C = (3.14)(20 ft) = 62.8 ft
__
The area is given by the formula ...
A = πr² . . . . . where radius r is half the diameter
Using the given numbers, the area is ...
A = 3.14(10 ft)² = 314 ft²
<h2>
Answer:</h2>
This is impossible to solve.
<h2>
Step-by-step explanation:</h2>
For an equation or inequality to be solvable, there must be the same number of inequalities as variables. Here, there is an x and there is a y. This means that you need at least two inequalities to solve it.
You can, however, rearrange to get x or y on one side.
This can be done for x:
5x < 10 + 2y
x < 2 + 2/5y
Or it can be done for y:
5x < 10 + 2y
5x - 10 < 2y
2.5x - 5 < y
Answer:
its B
Step-by-step explanation:
Answer:
-10
Step-by-step explanation:
= -X - XY
= -2 - 2×4
= -2 - 8
= -10
therefore, -X - XY = -10
