Triangles with height
and base
, with
have area
.
Such cross sections with the base of the triangle in the disk
(a disk with radius 5) have base with length

i.e. the vertical (in the
plane) distance between the top and bottom curves describing the circle
.
So when
, the cross section at that point has base

so that the area of the cross section would be 6^2/2 = 18.
In case it's relevant, the entire solid would have volume given by the integral

Answer:
2
Step-by-step explanation:
<span>Is that supposed to be:
(a²b³)⁴
If so, the exponent of an exponent is the product of the exponents, so we end up with:
a⁸b¹²</span>

Step-by-step explanation:
Find the perimeter of the garden find out what kind of triangle the garden is for example if it is a right triangle it has to equal up to 90.
To find the area remember that A=b•h2 as a=area
