Which represents r in terms of A and S?

Mathematics

ladessa [460]3 years ago

Answer:

r=\frac{6\sqrt{10AS}}{S\sqrt{\pi }}

Step-by-step explanation:

Given the formula;

A=\frac{\pi r^2S}{360}

We want to solve the given formula for r.

Multiply both sides by \frac{360}{\pi S}

A\times \frac{360}{\pi S}=\frac{\pi r^2S}{360} \times \frac{360}{\pi S}

A\times \frac{360}{\pi S}=r^2

Take square root of both sides

r=\sqrt{\frac{360A}{\pi S}}

r=\frac{\sqrt{360A}}{\sqrt{\pi S}}

r=\frac{\sqrt{360A}}{\sqrt{\pi }\sqrt{S}}

r=\frac{\sqrt{360A}\times \sqrt{S}}{\sqrt{\pi }\sqrt{S} \times \sqrt{S}}

r=\frac{\sqrt{360AS}}{S\sqrt{\pi }}

r=\frac{6\sqrt{10AS}}{S\sqrt{\pi }}

Mr. F is buying 8 computers for the computer lab. if one computer costs $1,156, How much will the computers cost in all?
Andreas93 [3]

answer: $9248


explanation:

well, we know the cost for one, so if each computer costs the same, multiply the cost of one of them by 8 to get the total.

8 x 1,156 = 9248.

so, we can assume this is what the computers will cost in total because there seems to be no added tax or fees.
