Step-by-step explanation:
we know that
The lateral area of a cone is equal to

where
r is the radius of the base
l is the slant height
we have


assume 
substitute the values

This value is an underestimate, because the assumed pi value is less than the real value
assumed value 
real value 
Answer:
x + y = 83
Step-by-step explanation:
When it says opposite angles are supplementary and yo use A as a reference point it means
supplementary means they add to 180
so
A + C = 180
so
2x + 4 + 2y + 10 = 180
now simplify
2x + 2y + 14 = 180
- 14 -14
2x + 2y = 166
/2 /2
x + y = 83
Answer:
92.5%
Step-by-step explanation:
shaded squares/total squares = 185/200
simplify:
(185/5)/(200/5) = 37/40
37/40= 35/40 + 2/40
32/40 + 5/40 = 4/5 + 1/8
4/5 + 1/8 = 0.8 + 0.125
0.8 + 0.125 = 80% + 12.5%
80% + 12.5% = 92.5%
It's one of the ways to count it:
3/4 (n + 3) = 9
3/4n + 3/4 * 3 = 9
3/4n + 9/4 = 9
3/4n + 2 1/4 = 9 / - 2 1/4 (both sides)
3/4n = 6 3/4 / : 3/4 (both sides)
n = 9
