Well first, we must remember the formula for the area of a circle.
The formula for the area of a circle is:
PiR^2, or Pi • R^2.
Basically this means 3.14 (Pi) • R • R (Radius).
We have our radius, 4, so we can plug in our numbers to solve.
3.14 • 4 • 4 is our formula, so let's solve.
4 • 4 = 16.
16 • 3.14 = 50.24.
Remember when we solve for the area, we use units squared (units^2).
Your answer is 50.24 cm^2.
I hope this helps!
You have to create and equivalent EXPRESSION in the equation that have equal bases then solve for x
SO THE ANSWER IS 12<span />
Answer:
x = 0.6623
y = 8
Image is attached for refernce of my solution
Step-by-step explanation:
In Δ DEF
By applying pythagoras theoram,
DE = 
=
∴ DE = 8
In Δ ABC
BC = y = 12 sin 30° = 6
AC =
+ DE + x =
+ 8 + x = 12 cos 30°
⇒ 9.73 + x = 10.39
<h3>⇒ x = 0.6623</h3>
Step-by-step explanation:






option B
Answer:
The correct option is 4.
Step-by-step explanation:
Let the line AB divided into 7 equal parts.
It is given that point P partitions the directed line segment from A to B in 3:4. It means 3 parts are before P and 4 partes are after P.
It is given that point Q partitions the directed line segment from A to B in 4:3. It means 4 parts are before Q and 3 partes are after Q.
It is given that point R partitions the directed line segment from A to B in2:5. It means 2 parts are before R and 5 partes are after R.
It is given that point S partitions the directed line segment from A to B in 5:2. It means 5 parts are before S and 2 partes are after S.
From the below figure we can say that point S is closest to point B.
It is also written as


Therefore option 4 is correct.
