Answer:

  • NQ = 3π units
  • sector area = 9π square units
  • 24 +3π units

Step-by-step explanation:

The formulas tell you for a circle of radius 6, ...

  C = 2π(6) = 12π

  A = πr² = π(6²) = 36π

__

a)

Arc NQ is 1/4 of the circumference of the circle, so will have length ...

  NQ = 1/4C = 1/4(12π)

  NQ = 3π . . . . units

__

b) Each sector is 1/4 the area of the circle. The area of one sector is ...

  sector area = 1/4A = 1/4(36π)

  sector area = 9π . . . . square units

__

c) The total path length is equal to the sum of the lengths of the pieces of the path length. Each radius is 6 units.

PRQNP = PR +RQ +QN +NP

  = PR +RQ +QN +NR +RP

  = 6 +6 +3π +6 +6

path length = 24 +3π . . . . units

__

Numerical answers (rounded to hundredths):

  NQ ≈ 9.42 u

  area ≈ 28.27 u²

  PRQNP = 33.42 u

If I have a triangular prism with the length of 9mm, the base of 6.6 mm, and the height 4 mm or 5.2 mm. What would be the surfac
Lelu [443]

The surface area of triangular prism is 117.12 mm²

<u>Explanation:</u>

Base side, a = 9 mm

Base side, b = 6.6 mm

Base side, c = 5.2 mm

Height, h = 4 mm

Total surface area = ?

We know,

Surface area, A = 2 Ab ( a+b+c) h

Ab = √s(s-a) (s-b) (s-c)

s = a+b+c/2

Solving for A

A = ah + b h + ch + 1/2 √ -a⁴ + 2(ab)² + 2(ac)² - b⁴ + 2 (b c)² - c⁴

A = 9.4 + 6.6 X 4 + 5.2 X 4 + 1//2 √ -9⁴ + 2(9 X 6.6)² + 2(9 X 5.2)² - (6.6)⁴ + 2 (6.6 X 5.2)² - (5.2)⁴

A = 117.12 mm²

Therefore, the surface area of triangular prism is 117.12 mm²

Jay caught two times as many fish as bob. together they caught 27 fish. how many fish did they each catch.
miv72 [106K]
Let Bobs catch be x, then Jay's catch is 2x.
x + 2x = 27
3x = 27
x = 27/3 = 9

Therefore, Jay caught 2 x 9 = 18 fishes and Bob caught 9 fishes.
