Complete question is;
An advertising banner has four sections, as modeled in the attached image. Two sections are congruent trapezoids, and two sections are congruent right triangles. Which measurement is the best estimate of the area of the banner in square meters?
Answer:
6 m²
Step-by-step explanation:
Since we are told that there are two congruent trapezoid, it means that they will have same base of 1m.
This Means the total base of the entire triangle will be;
Base = 1 + 1¾ + 1 + 1¾ = 5.5 m
Height of main triangle = 2 m
Thus,
Area = ½ × 5.5 × 2 = 5.5 m²
We are looking for best estimate, so let's approximate to the nearest whole number to get 6 m²
Answer:
The fair price for the large container is<u><em> $12</em></u>
Step-by-step explanation:
In this question, we are tasked with calculating what would be the fair price for the large cylinder given the price for the small cylinder.
To calculate this, what we need to do firstly is to estimate the the volumes of both cylinders.
Mathematically, the volume of a cylinder can be calculated using the formula; V = π ××h
For the small cylinder, r = 3 inches and h = 10 inches
Thus = π ×
× 10 = 90π
For the large cylinder, r = 6 inches and h = 10 inches
Thus = π ×
× 10 = 360π
Now let us find the ratio of their volumes = 360π/90π = 4
Since the ratio of their volumes is 4, it can be fair to say that the large cylinder should cost 4 times the price of the small cylinder = 4 × $3 = $12
