Solve for the radius

Mathematics
1 answer:
Mnenie [13.5K]3 years ago
7 0

To solve for the radius(r), you need to isolate/get the radius by itself in the equation:

A=\frac{1}{2} \pi r^2   Multiply the inverse of 1/2, which is 2/1 or 2 on both sides

(2)A=(2)\frac{1}{2} \pi r^2

2A = πr²     Divide π on both sides

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

\frac{2A}{\pi } =r^2     Now square root √ both sides to get "r" by itself

\sqrt{\frac{2A}{\pi } } =\sqrt{r^2}

\sqrt{\frac{2A}{\pi } } =r     Your answer is A

HELP PLEASE BEST ANSWER WILL BE MARK AS BRAINLIEST!
Gwar [14]
First of all,
The total weight of the six dogs are:
71+34+15+23+18+56=217 pounds
Then, we know that the average weight of the seven dogs are 40 pounds, so the total weights of the seven dogs are:
40×7=280 pounds.
Lastly, we know that the six dogs weights are 217 pounds and the total weight of the seven dogs are 280 dogs, so the seventh weight of the dog is:
280-217=63 pounds. As a result, the seventh weight of the dogs at the vet is 63 pounds. Hope it help!
