4.05 you multiply 2.25 times 1.8
D and b
they are 90° angles cause you can draw your line to make a 90° angle
Multiply the area of the circle by the percentage:
60 square units x 50% = 60 x 0.50 = 30
50% 0f the circle id 30 square units.
Answer:
1.875\pi square units
Step-by-step explanation:
We know that area of a circle is pi r square.
The sector has a proportional area according to the angle it subtends at the centre.
Here we have a circle of radius 3 inches with central angle 75 degrees.
Total angle of a circle = 360
Area of the given sector = Area of yellow shaded= 
Using proportions, it is found that 68 more people prefer vanilla than do strawberry.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching this problem on the internet, it is found that, out of 400 people:
- 18% preferred strawberry.
Hence the amounts are:
The difference is:
140 - 72 = 68.
68 more people prefer vanilla than do strawberry.
