Answer 1

Answer:

here is your answer .I hope this is helpful for you

Answer 2

Answer:

14  cm

Step-by-step explanation:

We know that:

Area of a Quadrant =1/4 area of the whole circle.

Therefore:

Area of a circle = πr²

Area of a quadrant = 1/4 x πr²

Given that:

Area of the quadrant = 38.5 cm²

Find the radius of the circle:

1/4 x πr²  = 38.5 cm²

πr²  = 154 cm²

r² = 49

r = √49 = 7 cm

Find the diameter:

Diameter = 2 x radius

Diameter = 2 x 7 = 14 cm
