Answer:

Answer:

114 cm²

Step-by-step explanation:

Area of shaded region

= area of circle -area of square

\boxed{area \: of \: circle = \pi {r}^{2} }

areaofcircle=πr

2

Given that radius= 10cm, r= 10cm.

\boxed{area \: of \: square = side \: \times side}

areaofsquare=side×side

Let the length of a side of the square be x cm.

Applying Pythagoras Theorem,

10² +10²= x²

100 +100= x²

x²= 200

x = \sqrt{200}x=

200

Area of square

= x²

= 200cm²

Area of shaded region

= 3.14(10²) -200

= 3.14(100) -200

= 314 -200

<h2>= 114 cm²</h2>

If h(x) = 2x4 - 4x2 - 2x, then h(3)= ? A) -6 B) 120 C) 192 D) 1146 E) 1434
garik1379 [7]

The value of h(3) is 120 ⇒ B

Step-by-step explanation:

To find the value of f(x) at x = a, do that

  • Substitute x by a
  • Find the value of f(a)

∵ h(x)=2x^{4}-4x^{2}-2x

- To find h(3) substitute x by 3

∴ h(3)=2(3)^{4}-4(3)^{2}-2(3)

∵ (3)^{4} = 81

∵ (3)² = 9

- Substitute them in the function above

∴ h(3) = 2(81) - 4(9) - 2(3)

∴ h(3) = 162 - 36 - 6

∴ h(3) = 120

The value of h(3) is 120

Marta is solving the equation s=2πrh+2πr^2 for h. which should be the result?
Marta_Voda [28]

Answer: First option.

Step-by-step explanation:

Marta needs to subtract 2\pi r^2 from  both sides of the equation:

s=2\pi rh+2\pi r^2

s- 2\pi r^2=2\pi rh+2\pi r^2- 2\pi r^2

s- 2\pi r^2=2\pi rh

Now she needs to divide both sides of the equation by 2\pi r, then:

h=\frac{s- 2\pi r^2}{2\pi r}

Rewriting:

h=\frac{s}{2\pi r}-\frac{2\pi r^2}{2\pi r}

Simplifying, she should get:

h=\frac{s}{2\pi r}-r

This matches with the first option.
