Answer:

96 cm²

Step-by-step explanation:

From the question,

s = (2πr∅/360)+2r................. Equation 1

Where s = Perimeter of a sector, r = radius, ∅ = angle subtend by the sector at the center of the circle.

Given: s = 40 cm, r = 8 cm

Constant : π = 3.14.

Substitute into equation 1 and solve for ∅

40 = (2×8×3.14×∅/360)+(2×8)

40 = (50.24∅/360)+16

40-16 = 50.24∅/360

50.24∅/360 = 24

50.24∅ = 24×360

50.24∅ = 8640

∅ = 8640/50.24

∅ = 171.97°

Area of a sector (A') = ∅πr²/360

A' = 171.97×3.14×8²/360

A' = 95.997

A' ≈ 96 cm²

9514 1404 393

Answer:

  a = 3

Step-by-step explanation:

Evaluating the given function at the point, we have ...

  f(-1) = a(-1)^2 +1 = 4

  a +1 = 4

  a = 3

The value of 'a' is 3.

Answer:

the area of the small square 4c

the total area of the 4 triangles is 2ab

a^2+2ab+b^2 = a^2+2ab+b^2

subtracting gives 2ab from both sides gives us a^2+b^2

Step-by-step explanation:

Answer:

Radius: R = 12 in

Diameter: D = 24 in

Circumference: C = 75.4in

Area: A = 452.39 in²

Step-by-step explanation:

Solutions:

Diameter d= 2r

D = 2 × 12

D = 24

Circumference

C = 2πr

C = 2 × π × 12

C = 24π

C = 75.3982237

Area:

A = πr²

A = π × 12²

A = 144π

A = 452.389342

Answer:

x = 65° + 60° = 125°

answer:'+' also means 'add'

It signifies a positive number, as described above, but it also means 'add' or 'plus'. For example 2+3 means 'two plus three' with a result of 5. Here, the plus-sign means addition. The same confusion happens with the minus ( – ) sign.

Answer:

B, 3 8/9

Step-by-step explanation:

It all comes down to equivalent fractions.

2 1/3 as an improper fraction is 7/3.

1 5/9 as an improper fraction is 14/9. 1/3 = 3/9.

With that being said 7 x 3 = 21 resulting in 21/9.

14/9 + 21/9 = 35/9.

35/9 as a mixed fraction is 3 8/9.
