Given the diameter of the surface of the clock, the area of the surface of the alarm clock is 3846.5cm².
<h3>What is the area of the alarm clock?</h3>
Note that: Area of a circle is expressed as;
A = πr²
Where r is radius and π is constant pi ( π = 3.14 )
Given that;
- Diameter d = 70cm
- Radius r = d/2 = 70cm/2 = 35cm
- Area = ?
A = πr²
A = 3.14 × ( 35cm )²
A = 3.14 × 1225cm²
A = 3846.5cm²
Therefore, given the diameter of the surface of the clock, the area of the surface of the alarm clock is 3846.5cm².

Answer:
NM = 15
Step-by-step explanation:
There is a property of secants and tangents to a circle where:
The square of the tangent length is equal the length of the external segment of the secant times the whole secant length.
Therefore, in our question, we have that:
The values of NM, ML and MK are:
So we have:
So the length of NM is:
Hello!
First of all let's subtract the cost of the serving dish.
69.77-18.25=51.52
Now we divide this cost by four.
51.52/4=12.88
Therefore, 1 plate costed $12.88.
I hope this helps!
