Question

If area of quadrant of a circle is 38.5 cm square then find itd diameter by study rankrr

Answer 1

Answer:

Diameter of the circle is 14.2 cm.

Step-by-step explanation:

Area of the quadrant of a circle is 38.5sq cm.

Total area of the circle = 38.5 ×4 = 154 squad cm.

Let the radius of the circle be R.

Therefore,

πR^2 =154.

R = √(154/π) = 7.1 cm.

Diameter of the circle = 7.1×2=14.2cm.

Answer 2

Answer:

Step-by-step explanation:

hey mate!!! here is your answer ........

area of quadrant = 1/4 *22/7*r²= 38.5(use π = 22/7)

radius = 7 cm

diameter = 14 ( 7*2)
