Answer:
The lateral area will be "381 yd²". A further solution is provided below.
Step-by-step explanation:
The given values are:
Radius of cone,
r = 10 yd
Height of cone,
L = 12.1 yd
As we know,
The lateral surface area of cone is:
=
On substituting the values, we get
=
=
=
0r,
=
He would have bought 2 small notebooks and 4 large notebooks. because $12×4= $48 and $6* 2 = $12. $48+$12=$60
<u>Answer:</u>
The standard form of the equation of the circle is
<u>Solution:</u>
Given, a circle has center (-8, 9) and x – axis as tangent.
First, let's determine r.
The center is 9 above the x-axis and the circle is tangent to the x-axis, so the radius r should be equal to 9.
The center moved 8 to the left, so substitute x by (x + 8).
The center moved 9 up, so substitute y by (y − 9).
You can determine these numbers by filling in the center coordinates, the outcome must be zero. [x+8=−8+8=0]
The standard equation
So, the equation becomes
Hence, standard form of the circle is
