This is just cylinder surface area, right? Equation for that would be 2πrh+2πr^2. If we input the data given from the image, it’d be (2 x π x 3.5 x 4)+(2 x π x 3.5 x 3.5). (4 is the height, and I found the radius by dividing the diameter, 7, in half, which is 3.5.) if u plug that into a calculator, u get 164.93.
Answer:
We need 4 topsoils
Step-by-step explanation:
I think your question is missed of key information that is the area of the flower bed, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
The flower bed is a triangle with its height is 5 cm and the base length is 12 cm, so we need to find out the area of it:
- S = Height*the base length = 5 * 12 = 60
So the bags of topsoil does Tom need to cover his flower bed is:
=
= 4
We need 4 topsoils
First, it is important to understand that parallel lines have the same slope. Therefore, based on the formula y=mx+b in which m represents slope and based on the equation y=-1/2x+5, the slope of the unknown line is also -1/2. Then, there are two different ways to solve this problem using different formulas.
The first method to find the unknown equation is easy but not widely known. We can use the point slope formula which is (y-y1)=m(x-x1) in which we can plug a point and slope to find the equation. When we plug in the values given, we get y+6=-1/2(x-4) or y+6 =-1/2x+2 which simplifies to y=-1/2x-4.
The other method is using the slope intercept form or y=mx+b. When we plug in our slope and our point, we get -6=-1/2*4+b or -6=-2+b so b must equal -4, therefore we have all the information we need to plug values into y=mx+b. When we plug in our slope and y-intercept, we get y=-1/2x-4 which is the answer.
I hope this helps!
60%
Ex:6+3+1=10
6/10 bows are purple
6/10 = 60/100 or 60%
What’s funnier that 24........ 25 lol sorry i’m d u m b
