Answer:
2,616.67cm³
Step-by-step explanation:
<em>Find the diagram attached</em>
volume of the cone = πr²h/3
r is the radius = 10cm
h is the height = 25cm
Substitute
V = 3.14(10)²*25/3
V = 314*25/3
V = 7850/3
V = 2,616.67cm³
Hence the volume of the cone to the nearest hundredth is 2,616.67cm³
Answer:
likely .
Step-by-step explanation:
It would take about 40 seconds for the temperature to reach 70°C and 44 second to reach 74°C.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the temperature of the metal bar after x seconds, hence:
Since the metal bar has an initial temperature of 30°C, hence:
b = 30, also m = 1°C (increase), The equation becomes:
y = 1(x) + 30 = x + 30
To reach 70°C:
70 = x + 30
x = 40 seconds
To reach 74°C:
74 = x + 30
x = 44 seconds
It would take about 40 seconds for the temperature to reach 70°C and 44 second to reach 74°C.
