Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = \sqrt{(4-(-1))^{2} + (-1-4)^{2} } = 5\sqrt{2} ≈ 7.1

BC = \sqrt{(0-(-1))^{2} + (-3-4)^{2} } = 5\sqrt{2} ≈ 7.1

CA = \sqrt{(0-4)^{2} + (-3-(-1))^{2} } = 2\sqrt{5} ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

Find the approximate volume of this prism.
musickatia [10]

Answer:

62m³

Step-by-step explanation:

The question is incomplete. Find the diagram of the prism attached below.

Volume of a Prism = Base area × Height

Given height = 9m

Since the prism is a triangular based prism,

Base area = area of the equilateral triangle = 1/2bh

base of the triangle = 4m

Height can be gotten using Pythagoras theorem.

Slant side of the triangle is the hypotenuse = 4m

Adjacent = 1/2 of the base = 1/2(4)= 2m

Height = √4²-2²

Height = √16-4

Height of the triangle= √12 m

Base Area = 1/2×4×√12

Base Area = 2√12 m

Volume of the prism = 2√12 × 9

= 2×2√3×9

= 36√3 m³

= 62.2m³

Volume of the prism is approximately 62m³

Probability of multiple events
vagabundo [1.1K]

Answer:

1/36

Step-by-step explanation:

A standard die has 6 faces

The numbers 1 through 6 on singly on each face

so the probability of tossing a 1 would be;

1/6

The probability of tossing another 1 would still be same 1/6

So the probability of tossing a 1 and another 1 would be the product of the two tosses as follows;

1/6 * 1/6 = 1/36
