area of the circle is 254.47yd^2

area of the circle is 254.47yd^2

Let R = radius of big circle

r=radius of small circle

A1=Area of small circle

A2=Area of big circle

R=9r

A1=50cm^2

A1=pi*r*2

A2=pi*R^2

A2=pi*(9r)^2

A2=81*pi*r^2

A2=81*A1

A2=4050cm^2

Hence the big circle has area of 4050cm^2

Step-by-step explanation:

Let R = radius of big circle

r=radius of small circle

A1=Area of small circle

A2=Area of big circle

R=9r

A1=50cm^2

A1=pi*r*2

A2=pi*R^2

A2=pi*(9r)^2

A2=81*pi*r^2

A2=81*A1

A2=4050cm^2

Hence the big circle has area of 4050cm^2

Step-by-step explanation:

the formula for the area of a circle is

πr²

plug 9 in for r (radius) to get

3.14 (81) = 254.34 cm² as our area

the circumference is equal to πd , with π being pi and d being diameter.

the circumference is then 3.14(100) = 314cm

Area of a Circle = 254.34 cm²

Step-by-step explanation:

Area of a Circle = π r²

Area of a Circle = 3.14 * 9²

Area of a Circle = 254.34 cm²

option B

Step-by-step explanation:

In terms of π

Area =πr²

Area=π×9²cm

Area=81π sq cm
