Answer:
160π cm²
Step-by-step explanation:
The area of the shaded region is
area of outer circle - area of inner circle
A = πr₁² - πr₂²
r₁ is the radius of the outer circle = 10 + 3 = 13 cm
r₂ is the radius of the inner circle = 3 cm
A = π × 13² - π × 3²
= π(169 - 9) = 160π cm² ≈ 502.65 cm² ( to 2 dec. places )
Answer:
Option D.
Step-by-step explanation:
Remember that
In a inscribed quadrilateral opposite angles are supplementary
so
In this problem
we have
substitute the values and solve for x
The answer is c. 43° because a bisector divides the angle in half
Answer:
for a = min -1 max 4
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Slope is y2-y1 over x2-x1
So:
4-2 = 2
-1+3= 2
so the slope here is 2/2 which we can simplify to 1
