Answer:
47.515 cm²
In meter square= 4.7515 *10^-3 m²
Explanation:
The radius of a circle = 5.5 cm
In meter= 5.5*0.01
= 0.055 m
the circumference= 34.56 cm
in meters = 34.56 cm*0.01
= 0.3456 meters
the area= 95.03 cm²
in square meters =95.03*(0.01)²
in square meters= 9.503*10^-3 m²
. area under the curve at the right
= Area of semi circle
= Area of circle/2
= 95.03 /2
= 47.515 cm²
In meter square= 4.7515 *10^-3 m²
10°c
Explanation:
Given parameter;
Lower fixed point = 30mm
Upper fixed point = 180mm
Reading = 45mm
Unknown:
The degree celcuis temperature at 45mm = ?
Solution:
To solve this problem we simply compare the mm- scale to the celcius - scale that we know.
The upper fixed point is the boiling point of water
Lower fixed point is the freezing point of water
This shows that both the upper and lower fixed point of both thermometers are the same;
mm-scale °c scale
180mm 100°c
45mm x
30mm 0°c
Solving;

x (150) = 100 x 15
x = 10°c

Answer: 49.5 m
Explanation:
The speed of sound
is given by a relation between the distance
and the time
:
(1)
Where:
is the speed of sound in air (taking into account this value may vary according to the medium the sound wave travels)
since we are told th hunter was initially 412.5 meters from the cliff and then moves a distance
towards the cliff
Since the time given as data (2.2 s) is the time it takes to the sound wave to travel from the hunter's gun and then go back to the position where the hunter is after being reflected by the cliff
Having this information clarified, let's isolate
and then find
:
(2)
(3)
Finding
:
This is the distance at which the hunter is from the cliff.

well I mean it would depend on where u live for this question that's the only reason I am confused.. I'm pretty sure it's A thi
