Question

please help i keep getting the wrong answers

Answer 1

Answer:

10 inches

Step-by-step 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

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

• $200\pi = \pi \times 10 \times (10 + l)$

• $\dfrac{200\pi}{10\pi} = 10 + l$

• $20 = 10 + l$

• $l = 10 \: in$

(note : " l " represents slant height.)

Therefore, Measure of slant height (l) :

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