Answer:
54.5 Sq. cm
Step-by-step explanation:
<em>area of a right angled triangle = 1/ 2 × base × height </em>
(here, the base is 8 and height is 6)
= 1/ 2 × 6 × 8
= 4 × 6
<u>= 24 Sq. cm</u>
<em>area of a circle</em> = r²
(r is the radius that is diameter/ 2, and the value of is 3. 14)
- r = 10/ 2 = 5 cm
= 3. 14.× (5)²
= 3.14 × 25
<u>= 78.5 Sq. cm</u>
area of the shaded region = area of Circle - area of triangle
= 78.5 - 24
<h3>= 54.5 Sq. cm</h3>that is option 3
Answer:
a)
b) 10
Step-by-step explanation:
a) Here
Since the case = ∇
holds, then
∇ =
So,
If we integrate with respect to x, we will get an integration constant C which is also a function that depends to y and z.
Hence,
Now we need to find g(y,z).
So first let's take the derivative of g(y,z) with respect to y.
Hence,
So now, if we integrate with respect to y to find g(y,z)
Thus,
And since , then
Thus,
b) By the Fundamental Theorem of Line Integrals, we know that
Hence,
