Answer:
B = log₃243 = 5
Step-by-step explanation:
By using the rule of aⁿ = b ==> logₐb = n, you can transform the exponent form into a logarithmic form by switching around the values of each letter to their desired place. It is interchangable between the two equations.
Answer:
39.30 
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/
)

where: θ is the central angle, and r is the radius.
Given that: central angle =
, radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/
)

=
x
x 
=
x
x 100
= 39.2857
= 39.30 
The area of the top surface of the wedge is 39.30
.
Answer:
Below are the three ways.
