Answer:
Option D - 10 inches
Step-by-step explanation:
Area of of a circle is given by the formula :
A = πr²
Area of a semicircle is given by the formula :
A = 1/2×πr²
Now we substitute our area value to solve for r :
50π = 1/2πr²
Multiply both sides by 2 :
100π = πr²
Divide both sides by π :
100 = r²
Square root both sides :
√100 = r
10 = r
Therefore our answer is option D of 10 inches
Hope this helped, thank you for the points and I may not be able to add your discord today but I have it saved.
Answer:
D
Step-by-step explanation:
Given :
⇒ Area = 50π in²
Formula :
Area (Semicircle) = 1/2 × πr²
Solving :
⇒ 50π = 1/2 × πr²
⇒ r² = 50π/π × 2
⇒ r² = 100
⇒ r = 10 inches
