Hello!
The base is shaped as a circle.
The formula for finding area of a circle ⇒ π · r²
The diameter is ½ of the radius.The diameter is 2. ½ of the diameter = 1
1² = 1 × 1 = 1
π = 3.14
1 × 3.14 = 3.14
Area ⇒ 3.14 square inches
Given: A= 52ft² and l= 2w-5
know that formula for A= lw, substitute for what you know and solve for w
52=(2w-5)w -> w= -4, w=6.5 but because a width measurement can not be negative, you can eliminate w=-4. so the width is equal to 6.5ft
now input that in the equation for length and solve for l:
l=2w-5=2(6.5)-5=8
so the length is 8 ft
Angle NLM is 78 degrees
A way to do this is to find the arc measure of NM and then divide it by 2 to find the angle of NLM
So first subtract
360-110=250
To find the remaining amount of the arc measures. Which is 250 degrees
Next set arc measures NM and ML together to 250 to find what x equals.
14x+16+9x+4=250
Combine like terms
23x+20=250
Subtract 20 from both sides
23x=230
Divide 23 from both sides
x=10.
Then substitute 10 for the equation representing the arc measure of NM.
14(10)+16
140+16
156
The arc measure of NM is 156 degrees
The angle NLM is an inscribed angle. Meaning that it is half of the arc that intersects.
156/2
78
Angle NLM is 78 degrees
