Answer:

-27

Step-by-step explanation:

Any operations inside parentheses must be carried out first.

Thus,

9 ÷ 3[(20 − 7) − 22] becomes 9 ÷ 3[(13) − 22]

This, in turn, becomes 9 ÷ 3[-9].

The negative operator can be taken out and written up front: -9 ÷ 3[9) Note: this does not call for subtraction).

Carrying out the indicated operations from left to right:

-3(9) = -27

PLS HELP ITS MY FINAL EXAM What is the area of the base of the cone below? A cone with height 12 feet and volume 90 feet cubed.

hoa [83]

Answer:

$A=22.5\ \text{feet}^2$

Step-by-step explanation:

We have,

Height of a cone is 12 feet

Volume of the cone is 90 feet

It is required to find the area of the base of the cone.

The base of a cone is circular in shape.

The formula used to find the volume of a cone is given by :

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

here, $\pi r^2=A$ (area of base of cone)

$V=\dfrac{1}{3}\times Ah\\\\A=\dfrac{3V}{h}\\\\A=\dfrac{3\times 90}{12}\\\\A=22.5\ \text{feet}^2$

So, the area of the base of the cone is $22.5\ \text{feet}^2$ .
