The function f(r) = π determines the area of a circle in cm2, A, in terms of the radius of the circle in cm, r. a. Write a function g that determines the radius of a circle in cm, r, in terms of the area of the cirlce in cm2,A. 9(A)t Preview syntax error b. Use function notation to answer the following questions: i. What is the area (in cm2) of a circle whose radius is 2.58 cm? Preview ii, What is the radius (in cm) of a circle whose area is 1530 cm? *Preview iii. How much greater is the area of a circle whose radius is 15.2 cm than the area of a circle whose radius is 15.1 cm?

Answer with Step-by-step explanation:

We are given that

a.

b.Radius=2.58 cm

Substitute the values in the formula and

Hence, the area of circle =20.9 square cm

c.Area of circle=1530 square cm

Hence, the radius of circle=22.07 cm

c.Area of circle of radius 15.2 cm=

Area of circle of radius 15.1 cm=

Hence, the area of circle whose radius is 15.2 cm is greater than the area of circle of radius 15.1 cm by 9.52 square cm .

it is part of the rising action that reveals public sentiment toward hester.

explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
