Answer:

A) 43.96 cm (Circumference)

B) 153.86 square cm (Area)

A) 62.8 ft (Circumference)

B) 314 square ft (Area)

Step-by-step explanation:

3. Radius 7 cm

7*2=14 (Find the diameter)

14*3.14= 43.96 cm (Circumference)

7*7=49 (Find the square of radius)

49*3.14 = 153.86 square cm (Area)

4. Diameter: 20 ft

20*3.14 = 62.8 ft (Circumference)

20/2=10

10*10=100

100*3.14= 314 square ft (Area)

weeeeeb [17]

<h3>Answer:</h3>

Number of students who chose history as favorite subject = 25

Number of students who chose music as favorite subject = 60

<h3>Step-by-step explanation:</h3>

Let the total number of students be 's'.

Number of students who chose history as favorite subject = $\frac{1}{6}$ of (Total number of students) = $\frac{1}{6}\times \textrm{s}$ = $\frac{1}{6}\textrm{s}$

Number of students who chose history as favorite subject = $\mathbf{\frac{1}{6}s}$

Number of students who chose music as favorite subjects = $\frac{2}{5}$ of (Total number of students) = $\frac{2}{5}\times \textrm{s}$ = $\frac{2}{5}\textrm{s}$

Number of students who chose music as favorite subjects = $\mathbf{\frac{2}{5}s}$

Number of students who chose neither history nor music as favorite subject = 65

Total number of students = (Number of students who chose history as favorite subject) + (Number of students who chose music as favorite subject) + (Number of students who chose neither history nor music as favorite subject)

$\mathrm{s=\frac{1}{6}s+\frac{2}{5}s+65}$
