Answer: Third red dot after 30 on the number line represents the approximate volume of a cone.
Step-by-step explanation:
Since we have have given that
Radius of cone = 3 units
Height of cone = 4 units
So, Volume of cone is given by
Hence, Third red dot after 30 on the number line represents the approximate volume of a cone.
Answer:
it cannot be simplified
Step-by-step explanation:
Answer:
16,6
Step-by-step explanation:
OK so I used the Sine Rule
(10÷Sin37) = (X÷Sin90) [Then cross multiply]
10Sin90 = XSin37
(10Sin90 ÷Sin37) = X = 16,62
<em>OB = 3 cm</em>
- Step-by-step explanation:
<em>AO = radius = 5 cm</em>
<em>AB = 8cm/2 = 4 cm</em>
<em>Pythagora</em>
<em>OB² = AO² - AB²</em>
<em>= (5cm)² - (4cm)²</em>
<em>= 25cm² - 16cm²</em>
<em>= 9 cm²</em>
<em>OB = √9cm²</em>
<em>= 3 cm</em>
