Answer:
Radius of the cylinder = 1.69 units
Step-by-step explanation:
Volume of a cylinder is given by the expression,
Volume = Area of the circular base × Height of the cylinder
Area of the circular base = πr²
Here, r = Radius of the circular base
Volume of the cylinder = πr²h
By substituting the values given in the question,
72 = π(r)²8
r² = 
r² = 2.865
r = 1.692
r = 1.69 units
2(pi)r = 9.4in
(pi)r = 4.7in
3.14r = 4.7in
r = 1.497in
Surface Area Of a Sphere = 4(pi)r^2 = [4(3.14)(1.497)^2]in^2 = 28.147in^2 = 28in^2
Volume Of a Sphere = 4/3(pi)r^3 = [4/3(3.14)(1.497)^3]in^3 =14.05in^3 = 14in^3
The temperature in a town up North was -8 degrees Fahrenheit. The next morning, it was 12 degrees Fahrenheit. How many degrees did the temperature rise?

Answer:
The length of the ladder = 6.5077 ft
Step-by-step explanation:
Given A ladder leans against the side of a house
Given the angle of elevation of the ladder is 68° when the bottom of the ladder is 16 ft from the side of the house
Let 'C' be the point of observation.
Given CA= 16 ft
From right angle triangle
x = 16 × cos 68°
x = 16 × 0.4067
x = 6.5077
x = 6.5 ft
The length of the ladder = 6.5 ft
