PLEASE HELP! :(

What is the surface area of the right cone below?

A≈606.32

Step-by-step explanation:

you need to use this equation: A=πr(r+h^2+r^2) to figure it out...

just plug your length, height, and radius in, and u have ur answer!!

ur answer shud be A≈606.32

Hope this helps!!

The surface area of the right cone is 176π sq unit. Option C.

Step-by-step explanation:

Given,

The radius (r) of the cone = 8 unit

Slant height (l) = 14 unit

To find the surface area of the right cone.

Formula

The surface area of the right cone = πrl+πr² sq unit

Now,

The surface area of the right cone = π×8×14+π×8² sq unit

= 112π+64π = 176π sq unit.

won't that be plagrisim thought?

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
