Answer:

the coordinates of the center of rotation is (4 , 3)

Step-by-step explanation:

*The line which passes through points (4 , 1) and (4 , 5) is vertical because the points have same x coordinates and its length is 5 - 1 = 4

*The line which passes through points (2 , 3) and (6 , 3) is horizontal because the points have same y coordinates and its length is 6 - 2 = 4

*These two lines intersect each other at their mid-point and this mid-point is the center of rotation

*The mid point is (\frac{4+4}{2},\frac{5+1}{2} )= (4,3)

 or (\frac{2+6}{2},\frac{3+3}{2}=(4,3)

The area of the base of the cone is 64π square millimeters, and the area of the lateral surface is 112π square millimeters. Find
baherus [9]

Answer:

Radius = 8 mm

Slant Height = 14 mm

Step-by-step explanation:

Base of a cone is a circle.

Area of circle is given as A=\pi r^{2}

Where r is the radius.

Given that

A = 64 \pi\ mm^2\\\Rightarrow  \pi r^{2} = 64\pi \\\Rightarrow r^{2}  = 64\\\Rightarrow r = 8\ mm

Hence, radius is 8 mm.

Formula for Lateral Surface Area of a cone:

LSA = \pi rl

Where r is the radius and

l is the slant height of cone

Given that LSA = 112 \pi\ mm^2

\Rightarrow 112\pi = \pi \times 8 \times l\\\Rightarrow 8 \times l = 112\\\Rightarrow l = 14\ mm

Hence, slant height is 14 mm
