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 funct
ollegr [7]

Answer with Step-by-step explanation:

We are given that

a.f(r)=\pi r^2

A=\pi r^2

r^2=\frac{A}{\pi}

g(A)=r=\sqrt{\frac{A}{\pi}}

b.Radius=2.58 cm

Substitute the values in the formula and \pi=3.14

f(2.58)=3.14(2.58)^2=20.9 cm^2

Hence, the area of circle =20.9 square cm

c.Area of circle=1530 square cm

r=\sqrt{\frac{1530}{3.14}}=22.07 cm

Hence, the radius of circle=22.07 cm

c.Area of circle of radius 15.2 cm=A_1=3.14(15.2)^2=725.47 cm^2

Area of circle of radius 15.1 cm=A_2=3.14(15.1)^2=715.95 cm^2

A_1-A_2=725.47-715.95=9.52 cm^2

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 .

pplzzz help me asap Stewart saves $15 a week for a college fund. This is ⅕ of his weekly pay. How much does Stewart make a week?
motikmotik

Answer:

$75

Step-by-step explanation:

Since $15 is one fifth of Stewart's weekly pay, we can multiply this 15 by 5 to find his full pay per week, which makes 15 x 5 = 75.

Hope this helps!
