Given the circumference of a circle is 26 pi, what is the area of the circle? Show work. Leave answer in term of pi.

Ierofanga [76]

Answer:169pi

Step-by-step explanation:

Circumference(c)=26pi

Circumference(c)=2 x pi x radius(r)

26pi=2pi x r

Divide both sides by 2pi

26pi/2pi=(2pi x r)/2pi

13=r

Radius(r)=13

Area of circle=pi x r^2

area of circle=pi x 13^2

Area of circle=169pi

What is the arc measure of DBC in degree

aliya0001 [1]

The length of both AB and DC is the same.

19 degrees

We want to know the arc measure for the whole circle, except for DC. So, we can subtract the arc measure of DC from 360 to find DBC. Since we found DC above, all we need to do is subtract.

360 - 19 = 341

DBC = 341 degrees

Hope this helps!! :)

Help me please. I am having troubles with my math homework.

Answer: (3) f(8) = g(8)

Step-by-step explanation:

Let's compare the values of f(x) and g(x) when x = 0, 2, 8, and 4

f(x) g(x) Comparison

f(x) = 2x - 3 $g(x)=\dfrac{3}{2}x+1$

f(0) = 2(0) - 3 $g(0)=\dfrac{3}{2}(0)+1$

= -3 = 1 f(0) < g(0)

f(2) = 2(2) - 3 $g(2)=\dfrac{3}{2}(2)+1$

= 1 = 4 f(2) < g(2)

f(8) = 2(8) - 3 $g(8)=\dfrac{3}{2}(8)+1$

= 13 = 13 f(8) = g(8)

f(4) = 2(4) - 3 $g(4)=\dfrac{3}{2}(4)+1$

= 5 = 7 f(4) < g(4)

The only statement provided that is true is f(8) = g(8)
