We are given the diameter of the circle, I assume. In this case, the formula of the area of the circle is expressed as A = pi d^2/4. where pi is a constant. The only option taht makes sense here is C. 6.25 in2. This should have the constant pi on it.
Answer:
Step-by-step explanation:
We have a function for x, what's the function for -2?
Plug in -2 and simplify
f(-2)=7(-2)-5
= -14-5
=-19

Answer:
r is 19
Step-by-step explanation:
-4 - 20 = -24
-24 - r = -5
r = 19
The reciprocal is just when you flip the number that you're given. the reciprocal of 7/12 is 12/7
Answer:
![x = 70^o](https://tex.z-dn.net/?f=x%20%20%3D%2070%5Eo)
Step-by-step explanation:
Given
See attachment for triangle
Required
Find x
To solve for x, we make use of:
--- angles in a triangle
![x + 110^o = 180^o](https://tex.z-dn.net/?f=x%20%2B%20110%5Eo%20%3D%20180%5Eo)
Collect like terms
![x = 180^o-110^o](https://tex.z-dn.net/?f=x%20%20%3D%20180%5Eo-110%5Eo)
![x = 70^o](https://tex.z-dn.net/?f=x%20%20%3D%2070%5Eo)
