(Please help ASAP 16 points! Thanks in advance!) solve -2a - 5 > 3
Bas_tet [7]

Answer:

a<-4

Step-by-step explanation:

To solve this, you have to isolate a. This means you will have to add 5 to both sides. This will make the equation -2a>8. Divide both sides by 2 to get -a>4. Divide each side by -1 to get a>-4. Because you have to flip the sign when you divide by a negative number, you have to change it into a<-4.

1. The formula for the volume of a cone is
Andre45 [30]

Answer:

r=\sqrt{\frac{3V}{\pi\ h}}

Step-by-step explanation:

The volume of cone is given by:

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

where r is the radius of the base and h is the height of the cone.

We need to solve for r

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

Multiplying both sides by 3 to remove \frac{1}{3}

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

⇒ 3V=\pi\ r^2\ h

dividing both sides by \pi\ h

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

⇒ \frac{3V}{\pi\ h}=r^2

Taking square root both sides:

⇒ \sqrt{\frac{3V}{\pi\ h}}=\sqrt{r^2}

⇒ \sqrt{\frac{3V}{\pi\ h}}=r

∴ r=\sqrt{\frac{3V}{\pi\ h}}

A cube block has sides 8cm long. A cylindrical hole of radius 3.6 is drilled through the block. Find the volume of the block tha
djverab [1.8K]

Answer:

186.45 cm^3

Step-by-step explanation:

Given data

Side lenght of cube block= 8cm

Radius of cylindrical hole= 3.6cm

Volume of entire Shape= l^3

Volume of entire Shape= 8*8*8

Volume of entire block= 512cm^3

Volume of cylindrical hole= πr^2h

Volume of cylindrical hole= 3.14*3.6^2*8

Volume of cylindrical hole= 3.14*12.96*8

Volume of cylindrical hole= 325.55cm^3

Hence the volume of the block

=volume of entire shape- volume of cylinder

=512-325.55

=186.45 cm^3
