Answer:
24.5672 cm² (answer rounded up to four decimal places)
Step-by-step explanation:
The area of the shaded region = The area of the circle with a diameter of 6.4 cm - the area of the two circles with diameters of 2.2 cm each
The area of the circle with a 6.4 cm diameter is:
Area(A) = π × r²
The radius here is = 3.2 cm
A = π × 3.2² = 32.1699087728 cm² or 32.1699 cm² (rounded up to four decimal places)
The area of the the circles with diameters of 2.2 cm each is:
Area(A) = π × r²
But because the circles are two, the area will be;
A = 2 × π × R²
The radius here is 2.2 cm ÷ 2 = 1.1 cm
A = 2 × π × 1.1² = 7.60265422169 cm² or 7.6027 cm² (rounded up to four decimal places)
The area of the shaded region = 32.1699 cm² - 7.6027 cm² = 24.5672 cm²
The complete table is
Dog Not Dog Total
Cat 31 10 41
Not cat 24 7 31
Total 55 17 72
Given a venn diagram represents the results of a survey that asked participants whether they would want a dog or a cat as a pet as shown in figure which is attached below.
In the figure cat and dog are overlapping which means 31 people like both.
The people that like only dog but not cat are 24 and the people that like only car but not dog is 10.
The people that like not cat not dog is 31-24=7.
The total people that like cats are 31+10=41 and the total people that dont like cat is 24+7=31
The total people that like dogs are 31+24=55 and the people that didn't like dogs are 31+10-24=17 and the total people that like both dog and not dog and also like cat and not cat is 55+17=41+31=72.
Hence, the complete table is shown in attached figure for the given venn diagram.
