Option A:
Lateral surface area = 1319 cm²
Solution:
Given image is the cone.
Radius of the cone = 15 cm
Slant height = 28 cm
Value of π = 3.14
<u>To find the lateral surface area of the cone:</u>
Lateral surface area = 

= 1318.8 cm²
Change this to nearest whole unit.
Lateral surface area = 1319 cm²
Hence the lateral surface area of the cone is 1319 cm².
Option A is the correct answer.
no way dude really? thats so cool
the reciprocal of 2 and 3/5 is 5/13
Answer:
87.92 m
Step-by-step explanation:
Formula for the circumference of a circle (which is what you're finding with this problem) is pi d
Pi being 3.14 and d being the diameter
Since the radius is 14 the diameter is 2 times that , 28m
Now just multiply 28 and 3.14 which gives you 87.92
Here's the formula:
(y2-y1)/(x2-x1)
so then:
(p-3)/(21-9)
so:
p-3/(12)
so then p = 7
