Answer:
w=10 feet
l=21feet
Step-by-step explanation:
let width be x
p=2l+2w
p=62
so we form the equation
l=1+2x
w=x
2(1+2x)+2(x)=62
2+4x+2x=62
6x=60
x=10feet
w=10feet
l=1+2x
l=21feet

Answer: 0.5
Step-by-step explanation:
L×L= area

Answer:
483.56 square milimeters
Step-by-step explanation:
In the above question, we obtain the following information:
Slant height = 15mm
Radius = 7mm
π = 3.14
Since we are given the slant height ,
the formula for surface area of a cone = πrl + πr²
= πr (l + r)
= 3.14 × 7(15 + 7)
= 3.14 × 7( 22)
= 21.98(22)
= 483.56 square milimeters
