If the circumference of the top of a hemispherical bowl is 44 mm, find the radius of the top of that bowl.
Answer & explanation
Correct answer: option 2
We know that,
Circumference of a circle = 2πR
We have,
The circumference of the top of a hemispherical bowl = 44 mm.
2πR = 44
R = \(\frac{44 × 7}{2 × 22}\)
R = 7 mm
