Find the area of the circle when C = π/6 . Give your answer in terms of π.
Harman [31]

Answer:

A = π/144

Step-by-step explanation:

The formula for the area of a circle is

A = πr²

Data:

C = π/6

Calculations:

1. Calculate the radius

C = 2πr

π/6 = 2πr

   π = 12πr

   1 = 12r

   r = 1/12  

2. Calculate the area

A = π(1/12)² = π/144

If f(x) = x + 4 and g(x) = x, what is (gºf)(-3)?
valina [46]

(gºf) means solve f(x) first, then use that for g(x)

In the equation for f(x) replace x with -3:

f(x) = x +4 = -3 +4 = 1

Now replace the x in the equation for g(x) with 1

g(x) = x = 1

Of 60 cities, 3 have a lake and 29 have a river running through them. What fraction of these 60 cities have a lake or river runn
nekit [7.7K]
Hello!

We know our denominator is 60, because that is the total amount of cities. Now, we must find our numerator:

3 + 29 = 32

Fraction: 32/60

You can simplify this by dividing both the numerator and denominator by 4:

32 ÷ 4 = 8 60 ÷ 4 = 15

FRACTION (SIMPLIFIED): 8/15

What equation will give the perimeter of the figure? HELP HELP HELP
nata0808 [166]

Answer:

(2l + 2w) + (a + b + c)

Step-by-step explanation:

The formula for the perimeter of a rectangle is

P = 2l + 2w

so if you substitute, it becomes

P = 2(12) + 2(2)

= 24 + 4

= 28

For the perimeter of a triangle the correct formula would be

P = a + b + c

The missing side in the triangle is 3 because 15 - 12 is 3.

If you substitute, it becomes

P = 2 + 3 + 6

P = 11

If we add both perimeters together we get the full perimeter of the figure which is

28 + 11 = 39

I am not sure if you wanted the answer as well but just in case :)
