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.

Step-by-step explanation:
I am sorry but please give detailed question
For a linear function, the instantaneous rate of change is everywhere equal to the slope. Thus the rate of change of the function h(x)=2x on the interval 2≤x≤4
The rate of change of the function given will equal to its slope, thus;
slope,m=(y-1-y)/(x_1-x)
=(2*4-2*2)/(4-2)
=(8-4)/2
=4/2
=2
the answer is 2
