Answer: <u><em>Diameter = 10cm</em></u>
<u><em>Circumference = 31.4cm</em></u>
<u><em>Area = 78.57cm2</em></u>
Step-by-step explanation: Radius = 5cm
→Diameter = 2×radius
= 2×5 = 10cm
Diameter = 10cm
→ Circumference = 2 ×22/7 × 5
= 220/7
=31.4cm
→ Area = 22/7 × 5 × 5
22/7× 25 = 78.57cm2

Answer:

The graph has a closed circle.
–7 is part of the solution.
Step-by-step explanation:
Given

Required
Select 3 options from the given list of options

Subtract 22 from both sides


Swap positions of the expression; Note that the inequality sign will change

This means <em>x less-than-or-equal-to negative 7</em>
<em></em>
There are two options left to select;
The inequality sign in
implies that the graph has a close circle.
Inequality signs such as
and
signifies a close circle
There is only one option left to select;
Lastly;
Split the expression
into two
We have:
or 
Because
,
Then, -7 is also a part of the solution
