A cone and its dimensions are shown in the diagram. What is the volume of the cone in cubic inches?

Vinvika [58]

Answer:

The exact value of the volume is equal to

$V=19\frac{397}{512}\pi\ in^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have

$D=5\frac{5}{8}\ in$

convert to an improper fraction

$D=5\frac{5}{8}\ in=\frac{5*8+5}{8}=\frac{45}{8}\ in$

$r=(45/8)/2=\frac{45}{16}\ in$

$h=7\frac{1}{2}\ in=\frac{7*2+1}{2}=\frac{15}{2}\ in$

substitute in the formula of volume

$V=\frac{1}{3}\pi (\frac{45}{16}^{2})(\frac{15}{2})=\frac{30,375}{1,536}\pi\ in^{3}$

Simplify

$\frac{30,375}{1,536}=\frac{29,184}{1,536}+\frac{1,191}{1,536}=19\frac{397}{512}$

substitute

$V=19\frac{397}{512}\pi\ in^{3}$

What is the product?<br><br> (6 r minus 1)(negative 8 r minus 3)

just olya [345]

Answer:

The required product is $-48r^2-10r+3$

Step-by-step explanation:

Consider the provided expression.

$(6r-1)(-8r-3)$

Open the parentheses.

$6r\left(-8r\right)+6r\left(-3\right)+\left(-1\right)\left(-8r\right)+\left(-1\right)\left(-3\right)$

$-6\cdot \:8rr-6\cdot \:3r+1\cdot \:8r+1\cdot \:3$

$-48r^2-18r+8r+3$

Add the like terms.

$-48r^2-10r+3$

Hence, the required product is $-48r^2-10r+3$

What is the length of the base of a right triangle with an area of 24m and a height of 4m

insens350 [35]

To find the length of the base, we have to understand that area of triangle:

Base x height/2

Therefore we would multiply the area by 2 and divide by 4 to find the answer:

24x2/4

=48/4

=12

Therefore the answer is 12m.

Hope it helps!
