Area of the circle is 200.96 cm²

Step-by-step explanation:

  • Step 1: Calculate area of the circle using the formula, A = π × r². Here r = 8cm.

⇒ Area = 3.14 × 8 × 8 = 200.96 cm²

Since Y is the right angle of the triangle LNT, LT is the hypotenuse of that triangle. We are going to use the Pythagorean equation to find the measure of LT:
LT= \sqrt{LY^2+TY^2}
LT= \sqrt{5.2^2+3.9^2}
LT=6.5

We can infer from our picture that triangles LNT and YNT are similar. And remember that in similar triangles <span>the corresponding sides are proportional, so we can establish a proportion between sides LT and NT, and between sides  LY and TY:
</span>\frac{LT}{NT} = \frac{LY}{TY}
\frac{6.5}{NT} = \frac{5.2}{3.9}
<span>Solving for NT:
</span>NT= \frac{(6.5)(3.9)}{(5.2)}
NT=4.88
<span>
Now the perimeter of our rectangle LINT will be 2LT + 2NT. 
</span>2(LT)+2(NT)=2(6.5)+2(4.88)=22.76<span>
</span><span>
We can conclude that the perimeter of the rectangle LINT is 22.76 units</span><span>

Line 'L' is horizontal and passes through (-5,8). Line 'L is vertical and passes through $(4,-1)$. Find the point of intersectio
Elanso [62]
<h3>The two lines intersect at (4,8)</h3>

Every y coordinate on the horizontal line is the same, so each point has a y coordinate of y = 8. This is to be able to pass through (-5,8)

Every x coordinate on the vertical line is the same, so each point has an x coordinate of x = 4. This is to be able to pass through (4,-1)

Put this together to get the answer (x,y) = (4,8)

Let B be between a and C use the segment addition postulate to solve for W
fomenos

Answer:

Value of w = 6

Step-by-step explanation:

Given:

AB= 4w-4

BC = 2w-8

AC = 24

Find:

Value of w

Computation:

AB + BC = AC

4w - 4 + 2w - 8 = 24

6w - 12 = 24

6w = 24 + 12

6w = 36

w = 6

Value of w = 6
