Question

Please help i keep getting the wrong answers

Answer 1

10 inches

Explanation:

Surface Area = π R² + π R L [ L is Slant Height ]

200 π = π (10)² + π (10) L

200 π = π (100) + π (10) L

200 π - 100 π = 10 π L

100 π = 10 π L

100 π / 10 π = L

10 = L

L = 10 inches

Hope this Helps......

Answer 2

`\huge{ \mathrm{  \underline{ Answer} \:  \:  ✓ }}`

Given terms :

• Surface area (a) = 200 π

• radius = 10 inches

Now, we know

`\large\boxed{\mathrm{surface \: \: area = \: \pi r(l + r) }}`

• 
  `200\pi = \pi * 10 * (10 + l)`

• 
  `(200\pi)/(10\pi) = 10 + l`

• 
  `20 = 10 + l`

• 
  `l = 10 \: in`

(note : " l " represents slant height.)

Therefore, Measure of slant height (l) :

`\huge \boxed{10 \: \: in \: }`
