Answer:
24 units ²
Step-by-step explanation:
In this problem, we are given the circumference of a triangle (after finding the perimeter) and want to find the area of a circle with that circumference. Since the area of a circle is a function based on its radius, we can use the circumference to find the radius to find the area.
First, we can figure out the perimeter of the triangle, which is equal to the sum of its sides. The perimeter is 6+4+7.21 = 17.21 units.
Next, the circumference of a circle is equal to π * diameter = π * 2 * radius. Using 3.14 for π and r for radius, we get
3.14 * 2 * r = 17.21
6.28 * r = 17.21
divide both sides by 6.28 to isolate r
r ≈ 2.74
Furthermore, to find the area from the radius, we can use
area = πr². Plugging 2.74 in for r, we get
2.74² * 3.14 = area
≈23.6, rounding up to 24 units ²
Answer:
140 ml is needed to give 10.5g of Gantrisin
Step-by-step explanation:
In this question, we are asked to calculate how many milliliters liters will give a certain mass of Gantrisin.
Firstly, from the first values given, we can calculate the value if the density of the liquid.
Mathematically, the value of the density can be calculated by ;
Density = mass/volume = 1.5g / 20ml = 0.075 g/ml
Now for the second part of the question, we have the mass, but we do not know the volume. We can use the calculated density to know this.
We use the formula
volume = mass/density
Volume = 10.5g/(0.075g/ml)
Volume = 140 ml
Given:
Right triangle with one angle 45°
To find:
The value of q and r.
Solution:
Opposite to θ = 16
Adjacent to θ = r
Hypotenuse = q
Using trigonometric ratio formula:
The value of tan 45° = 1
Do cross multiplication, we get
r = 16
Using trigonometric ratio formula:
The value of sin 45° = 
.
Do cross multiplication, we get
The value of r is 16 and the value of q is 
.
