What is the approximate volume of a cone with a radius of 15 cm and a height of 4 cm? Round your answer to the nearest hundredth
vichka [17]

Answer:

Volume of a cone =942.86cm^3

Step-by-step explanation:

Given that the radius of a cone is 15cm and its height is 4cm

That is r=15cm and h=4cm

To find the volume of a cone :

volume of a cone=\frac{\pi r^2h}{3} cubic units

Now substitute the values in the formula we get

volume of a cone=\frac{(\frac{22}{7}) (15)^2(4)}{3}  

=\frac{(\frac{22}{7}) (225)(4)}{3}

=\frac{19800}{21}

=942.857

Now round to nearest hundredth

=942.86

Therefore Volume of a cone=942.86cm^3

When determining if you have a perfect square trinomial, what must the first and third term be?
cricket20 [7]

The expansion of a perfect square is

(a+b)^2 = a^2+2ab+b^2

In words, the square of a sum of two terms is the sum of the squares of the two terms (a^2 and b^2), plus twice the product of the two terms (2ab)

So, when determining if you have a perfect square trinomial, you should have two perfect squares. Note that they don't have to be the first and third term, since you can rearrange terms as you prefer.

Using the distributive property write a numerical expression that is equivalent to 25+10
Diano4ka-milaya [45]

Answer: 5(5 + 2)

Step-by-step explanation: We will be using the distributive property to write a numerical expression that is equivalent to 25 + 10.

The expression 5(5 + 2) is an expression that uses the distributive property and is equivalent to 25 + 10.

5(5 + 2) is equivalent to 25 + 10 because all your doing when using the distributive property is multiply the number outside the parentheses by the numbers inside the parentheses. 5 x 5 = 25 and 5 x 2 = 10, which means 5(5 + 2) equals 25 + 10.
