13.20254313. Pi(2.05)^2. 4.1÷2(for the radius)=2.05.Square it and multiply by Pi. a=pi(r)^2
The equation that can be used to determine the value of x is Option B.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement formed when two algebraic expression are equated by an equal sign.
From the diagram ,
A straight line has an angle of 180 degree.
Therefore from the figure
To determine the value of x
2x + 4x = 180
6x = 180
x =30 degree
Thus the equation that can be used to determine the value of x is Option B.

Answer: the answer is 2 and 1/15
Step-by-step explanation:
Answer:
The first answer choice: 15 cm x 3.14 cm x 2cm^2 = 188.4 cm^3
Step-by-step explanation:
Formula:
V=πr^2h
radius=2
height=15
V=π(2)^2*15
π(4)*15
4*15=60
60π
π=3.14
60(3.14)
188.4
Since its volume you have to cube it
188.4 cm^3
7 ÷ 1/8 = 56
1/8 = 0.125.
When you are dividing fractions, to work them out you flip the fraction (or second fraction if there is 2) and change the sign. In this case, that would be 7 x 8/1.
7 x 8 = 56
56 / 1 = 56
