The measure of EF from the given diagram is 6 units
<h3>Secant secant theorem</h3>
The theorem states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external parts is the same as the product of the other external part.
Mathematically according to the given figure;
4(4+2x) = 5(5+x)
Expand
16 + 8x = 25 + 5x
Collect the like terms
8x - 5x = 25 - 16
3x = 9
Divide both sides by 3
3x/3=. 9/3
x = 3
Find EF
EF = 2x
EF = 2(3) = 6
Hence the measure of EF from the given diagram is 6 units

Answer:
x² + y² = 4
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius]Here r = 2, thus
x² + y² = 4
Answer:
Price of paint = Rs 16,640
Step-by-step explanation:
As 3 dimensions are given so the third one must be for ceiling.
So in this case, we can find area as follows:
Area = 2(length * width) + 2(length * height)+ 2(height * width)........eq1
Lets say:
Length = 8m
Width = 6m
Height = 4m
So putting value in eq1 we get:
Area = 2(8*6) + 2(8*4) + 2(4*6)
Area = 2(48) + 2(32)+ 2(24)
Area =96 + 64 + 48
Area = 208 sq. m
Now for calculating price:
Price of paint = 208 * 80
Price of paint = Rs 16,640
