Answer:
Area of the triangle covered by the cars = 910.45 square km
Step-by-step explanation:
Since, all the sides of triangle ABC are given,
And formula for the area of a triangle with all sides given is,
Area =
Here, s =
And a, b, c are the measures of the sides of the triangle.
If a = 39 km, b = 87 km and c = 58 km
s =
s = 92
Therefore, (s - a) = 92 - 39
= 53
(s - b) = 92 - 87
= 5
(s - c) = 92 - 58
= 34
Now area of the triangle ABC =
=
= 910.45 km²
Area of the triangle covered by the cars = 910.45 square km
Y = X/2 is directly proportional
Y = 2/X is not directly proportional
Hope this helps! :)
The volume of the prism is 9 in³.
<h3 /><h3>What is a prism?</h3>
A prism is a 3-dimensional shape, with two identical shapes facing each other.
To calculate the volume of the prism, we use the formula below.
Formula:
- The volume of the prism (V) = 72×volume of one cube
- V = 72L³............. Equation 1
Where:
- V = Volume of the prism
- L = Length of the cube
From the question,
Given:
Substitute these values into equation 1
- V = 72(1/2)³
- V = 72(1/8)
- V = 9 in³
Hence, the volume of the prism is 9 in³.
