Hi there! The formula for circumference is π * diameter. Diameter is the length across the circle and twice the length of the radius.The radius is 5.4, so we will multiply that by 2 to get 10.8. The diameter is 10.8 inches. Now, multiply that numebr by 3.14 to find the circumference. 10.8 * 3.14 is 33.912 or 33.9 when rounded to the nearest tenth. There. The circumference is approx. 33.9 inches.
The area of the sector is
.. Asector = (1/2)r^2*θ = (1/2)*(8.35 ft)^2*(π*260°/180°) ≈ 158.195 ft^2
The area of the triangle is
.. Atriangle = (1/2)r^2*sin(θ) = (1/2)*(8.35 ft)^2*sin(100°) ≈ 34.332 ft^2
The shaded area is
.. A = Asector +Atriangle
.. = 158.195 ft^2 +34.332 ft^2
.. ≈ 192.5 ft^2
The answer is b.) (10x+1)^2
Answer:
x=−9
Step-by-step explanation:
Let's solve your equation step-by-step.
x+5=2(7+x)
Step 1: Simplify both sides of the equation.
x+5=2(7+x)
x+5=(2)(7)+(2)(x)(Distribute)
x+5=14+2x
x+5=2x+14
Step 2: Subtract 2x from both sides.
x+5−2x=2x+14−2x
−x+5=14
Step 3: Subtract 5 from both sides.
−x+5−5=14−5
−x=9
Step 4: Divide both sides by -1.
−x
−1
=
9
−1
x=−9
