1. The formula for calculate the area of a cone is:
A=πr²+πrl (1)
A is the area (A=395.64 m²).
π=3.14
r is the radius (r=7).
l is the height.
2. The formula for calculate the slant height of the cone, is given by the Pythagorean theorem:
h²=l²+r²
h=√(l²+r²) (2)
h is the slant height.
3. We don't know the value of "l", so:
- We must rewrite the formula (1) and clear "l":
A=πr²+πrl
A-πr²=πrl
l=A-πr²/πr
- Now, we must susbtitute l=A-πr²/πr, into the formula (2). Then, we have:
h=√(l²+r²)
h=√[(A-πr²/πr)²+r²]
A=395.64 m²
π=3.14
r=7
4. When we substitute the values above into the formula h=√[(A-πr²/πr)²+r²], we obtain the slant height:
h=√[(A-πr²/πr)²+r²]
h=√170
h=13

What is the slant height?
The answer is: D.13</span>
1 cm = 10 mm
? cm = 987 mm
987/10 = ? cm = 98.7 cm.
There are 98.7 cm in 987 mm.
Answer: 170.37 acres
Step-by-step explanation:
In 2005, x= 2005
Substituting x=2005 in the equation.
A(2005) = (2078x-94458)/(13x-2164)
A(2005) = 4071932/23901
A(2005) = 170.37 acres
Answer:
58
Step-by-step explanation:
As there are 12 teams in the league and each teams plays every other team twice per season. so, the total number of matches in the league will be 132.
let the matches won by home team = 'x'
given,
number of matches drawn = 34
matches won by the away team = x - 18
Now, according to the question,
⇒ total matches = matches drawn + matches won by home team + matches won by away team
⇒ 132 = 34 + x + x -18
⇒ x = 58
Instead of negative positive and instead of positive negative hope you get it right. Am not that smart
