Given:
The radius of the base of the given cone = 5 cm
The slant height of the cone = 19 cm
To find the surface area of the given cone.
Formula
The surface area pf the given cone is,
where, r be the radius and
l be the slant height.
Now,
Taking, r = 5, l = 19 and π = 3.14 we get,
sq cm
or, sq cm
or, sq cm
Rounding off to the nearest square centimeter, we get;
Hence,
The surface area of the cone is 377 sq cm.
Answer:
314
Step-by-step explanation:
Answer:
if area is given than use formula=πd²/4
if circumference=πd
Answer:
-24
Step-by-step explanation:
It’s the first answer, 38.
(4x+4)+(5x-22)=90
9x-18=90
9x=72
x=8
4(8)+4=38
I hope this helps :)
