Answer:

28.3

Step-by-step explanation:

Hello!

To find the area of a circle we use πr².

In this case, all we have to do is divide 6 by 2 and square that.

6 ÷ 2 = 3. 3² = 9.

9 × π = 28.2743....

Rounding to the nearest tenth:

28.3

Thus, the area of the circle is $\boxed{28.3}$ .

Hope this helps!

Answer:

28.27

Step-by-step explanation:

Area= pi x radius squared

Radius is 1/2 the diameter which in this case is 6 ft

So, pi x 3 squared (9)

= 28.27

Hector is dividing students into groups for an HR wants to divide the boys and girls so that each group has the same number of t

Roman55 [17]

Answer:

7 groups, 3 boys and 8 girls

Step-by-step explanation:

Let total number of groups be $x$

and total hikers in one group be $y$

if number of girls and boys in every group is same, then

$\frac{21}{x} + \frac{56}{x} = y$

$\frac{21 + 56}{x} = y\\x*y = 77$ ....(1)

from (1) $x$ will either be 11 or 7

for $x = 11$ the values won't be real.

For $x = 7\\y = \frac{77}{7} \\y = 11$

so there will be 7 groups with 11 hikers in each groups and every group will have $\frac{21}{7} = 3$ boys and $\frac{56}{7} = 8$ girls

Simora [160]

Answer:

2a - b = 5

Step-by-step explanation:

4a - 2b = 10

take out the highest common factor of the left side

2(2a - b) = 10

divide both sides by two

2a - b = 10/2

2a - b = 5
