Hey mate, um if u need help graphing lines or graphs in maths, there is this graph drawing website called DESMOS, so just copy and paste your equation into the grapher and it will graph it for you.
It is a really helpful website.

Answer:
V = 240π cm^3 , S= 168π cm^2
Step-by-step explanation:
The given figure is a combination of hemi-sphere and a cone
<u>Volume:</u>
For volume
r = 6 cm
h = 8 cm

<u>Surface Area:</u>
For this particular figure we have to consider the lateral area of the cone shape and surface area of the hemisphere
We have to find the lateral height

Hence the first option is correct ..
A parabola, a graph of a quadratic function, cannot have a maximum vertex and a minimum vertex at the same time because of the shape of the graph. A parabola is a u-shaped graph. The vertex of the parabola is the point where the u changes direction; if it was increasing, it starts to decrease, and if it was decreasing, it starts to increase. Since a parabola only changes direction once, there will either be a minimum or a maximum, not both.

Answer:
X and Y = 66.5°.
Step-by-step explanation:
I am assuming that X and Y are the base angles, which are equal in an isosceles triangle.
X = Y = (180 - 47) / 2
= 66.5°.
