Use the net to find the approximate surface area of the cylinder to the nearest square meter.

Step-by-step explanation:

radius r of cylinder = 7

circumference of cylinder = 2πr = 14π meters.

lateral area of cylinder = 14π×11 = 154π m².  This is represented by the rectangle.

area of top = πr² = 49π m²

area of bottom = area of top = 49π m²

total surface area = lateral area + 2(top area) = 154π + 2×49π = 252π ≅ 792 m²

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
