Two circles have the same radius. Complete the description for whether the combined area of the two circles is the same as the area of a circle with twice the radius. The combined area of two circles with the same radius is ___πr2. The area of a circle with twice the radius is ___πr2. The combined area of two circles is as the area of a circle with twice the radius.

see below

Step-by-step explanation:

A = pi r^2

If they have the same radius they have the same area

A two circles = pi r^2 +pi r^2

                      = 2 pi r^2

If we double the radius

A = pi (2r)^2

   = pi 4r^2

The combined area of two circles is  1/2  the area as the area of a circle with twice the radius.

'is not some as'

Step-by-step explanation:

Let r be the radius of one circle:

Area of 2 circles = 2(pi×r²) = 2pi×r²

Double the radius: 2r

Area = pi × (2r)² = pi × 4r² = 4pi×r²

step-by-step explanation:

10.50 + taxes which added up to 11.50

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
