What are the circumference and area of a circle with radius 7in. Round to the nearest tenth.

Circumference is 40 in and area is 150 in²

Step-by-step explanation:

Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in

Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²

answer: was that a question or answer?

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
