Question

CAN SOMEONE PLS HELP ME 10 POINTS PLS

Answer 1

Answer:

2,700 in^2 ; Option D

Step-by-step explanation:

If it is known that the diameter of Circle B ⇒ 60 inches,

$Diameter - 60 inches,\\\\Radius - 60 / 2 = 30 inches,\\\\Area of Circle B ( \pi stands for 3 ) - \pi * ( r )^2 = ( 3 ) * ( 30 )^2 = ( About ) 2,700 square inches\\\\Solution; 2,700 square inches$

( About ) 2,700 square inches; Option D

Answer 2

Answer:

D) About 2,700 in^2

Step-by-step explanation:

Equation for area of a circle is A=3r² (it would usually be A=πr² but we are using the approximation)

The diameter is 60, we want to find the radius for the equation. We can use the equation d=2r to find the radius of the circle.

60=2r

30=r

Put radius into the area equation.

A=3(30)²

A=3(900)

A=2700
