Answer:
5.1 cm²
Step-by-step explanation:
The area of a segment is given by the formula ...
A = 1/2r²(α -sin(α)) . . . . . where α is the central angle in radians
For this segment, its area is ...
A = 1/2(6 cm)²(7π/18 -sin(70°)) ≈ 5.077 cm²
The area of the segment is about 5.1 square centimeters.
_____
The angle is converted to radians by multiplying by π/180°. Then a 70° angle is π(70°/180°) = 7π/18 radians.
We know that
<span>pentagon A is the smaller pentagon----> length side 4 cm
and
</span><span>pentagon B is the larger pentagon-----> length side 6 cm
so
</span><span>the scale factor from pentagon B to pentagon A=length side B/length side A
6/4----> 3/2---> 1.5
the answer is the option
</span><span>B) 1.5 </span>
(r*s) = (x+1)(3x+4) = 3x² + 3x + 4x + 4 = 3x² + 7x + 4
(r-s)(x) = x+1 - (3x+4) = x + 1 - 3x - 4 = -2x - 3
(r+s)(x) = x + 1 + 3x + 4 = 4x + 5
(r + s)(2) = 4(2) + 5 = 8 + 5 = 13
<h3>What is algebraic expression?</h3>
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation. Word illustration: The product of 8 and 3. Word illustration: The product of 8 and 3 is 11
