Find the surface area of the cone in terms of pi.

Nana76 [90]

Surface area of cone is 60π cm^2

Option A is correct.

Step-by-step explanation:

We are given:

Height = 17cm

Radius= 3cm

We need to find surface area of cone in terms of π.

The formula used to find surface area of cone is:

$Surface\,\,area\,\,of\,\,cone=\pi r(r+\sqrt{h^2+r^2})$

Putting values:

$Surface\,\,area\,\,of\,\,cone=\pi r(r+\sqrt{h^2+r^2}) \\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+\sqrt{(17)^2+(3)^2})\\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+\sqrt{289+9)}\\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+\sqrt{298)}\\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+17)\\Surface\,\,area\,\,of\,\,cone=\pi \,3(20)\\ Surface\,\,area\,\,of\,\,cone=60\pi$

So, Surface area of cone is 60π cm^2

Option A is correct.

Mr. Stewart has 26 students in his class. Ten of his students are girls. If Mr. Stewart writes each student's name on a small st

swat32

Answer:

8/13

Step-by-step explanation:

Step 1 : Write all the data

Total number of students = 26

Number of girls in class = 10

Number of boys in class = 26-10 = 16

Step 2 : Find the probability

Probability of pulling out a boy's name = number of boys in class

Total number of students in class

= 16/26

Simplify :

16/26 = 8/13

I hope this helps you

f (x)=x^2 (x^2-1)

f (x)=x^2 (x-1)(x+1)
