The radius of a cone with a curved surface area of 140π cm² and a slant height of 5 cm will be 28 cm.
<h3>What is curved surface area?</h3>
The region with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area. Total Surface Area is the combined area of the bases and the curved surface. The measurement of a solid's curved surface area is its outer area, which excludes the top and bottom extensions. Surface area of the cylinder that is curved: A right circular cylinder is the solid that results when a rectangle circles around one side and makes a full revolution. The curved surface area of a cylinder (CSA) is also known as the lateral surface area and is defined as the area of the curved surface of any given cylinder having a base radius "r" and height "h".
Here,
Curved surface area of cone=πrl
=140π
l=5 cm
140π=πr*5
r=140/5
r=28 cm
The radius of cone that has 5 cm as slant height and 140π cm² as the curved surface area will be 28 cm.

I believe you meant to say that if Samantha bought 510 pounds of hamburger, how much will she pay?
Now from the information we already have, we know that 3 pounds of hamburger will cost 6 dollars.
The next thing we need to know is how much one pound of hamburger will cost. This will help us calculate how much the rest will cost.
we now form an equation to assist us.
3 = 6
1= x
(where x represents the unknown price of one pound of hamburger)
Now we must cross-multiply:
3 * x = 6 x 1
3x = 6
x = 6/3
x = 2
therefore one pound of hamburger costs 2 dollars.
Now, If one pound costs 2 dollars, how about 510 pounds?
We simply multiply: 510 x 2 = 1,020
Therefore Samantha will pay 1, 020 dollars for 510 pounds of hamburger.
Answer:
in my opinion I think it parallelogram because it has four sides which are A,B,C,D
Answer:
y is less than or equal to 2/3x + 1/5
Step-by-step explanation:
528= 8x+240
288=8x
x=36 hours
