Answer:
I. Volume = 301.6 cm³ (to 1d.p)
II. CSA = 188.5 cm² (to 1d.p)
Step-by-step explanation:
<u>Given the following data;</u>
Height, h = 8cm
Radius, r = 6cm
Curved length = 10cm
a. To find the volume of the cone
Where;
- V is the volume of the cone.
- r is the radius of the base of the cone.
- h is the height of the cone.
Substituting into the equation, we have;
<em>Volume = 301.6 cm³</em><em> </em>(to 1d.p)
b. The curved surface area of the cone
Where;
- CSA is the curved surface area of the cone.
- r is the radius of the base of the cone.
- l is the curved length of the cone.
Substituting into the equation, we have;

<em>CSA = 188.5 cm²</em> (to 1d.p)

Answer:
Option 1.
Step-by-step explanation:
It's option 1.
You divide (b/a) by 2 then square it, then subtract this from both sides of the equation. It is the process of Completing the Square.
Since the denominator is 33 specifically, a trick I learned is that almost any number that is the numerator is repeated as a decimal if it is multiplied by three. If it is 6/33, the decimal is 0.181818181818....... and if it is 8/33, then it is 0.242424242424..... Using logic now, you can see that 7/33 is 0.212121212121.........
