A right cone with a radius of 4 inches and a square pyramid both have a slant height of 5 inches. Both solids have the same surface area. Find the length of a base edge of the pyramid. Round your answer to the nearest hundredth.

Answers

Answer 1

Answer: The surface area of the cone is given by:
SA=πrl
Thus the surface area of the cone will be:
SA=π×4×5
SA=20π=63.932

Surface area of the pyramid is given by:
SA=1/2×4×(b×l)
thus the base length will be:
63.932=10l
thus
l=6.3932 in

Simplify \sqrt{25a^2}

Answers

Final Answer: 5a

Explanation:

Sure! Let's simplify this step by step.

Given \sqrt{25a^2}

Step 1: Recognize that the given expression \sqrt{25a^2} represents the square root of 25 times the square of 'a'.

Step 2: Break down the expression into two parts. We have a perfect square (25) and a square term (a^2). We can separate these inside the root as follows:

\sqrt{25} * \sqrt{a^2}

Step 3: Simplify \sqrt{25}. Since 25 is a perfect square, its square root is 5. Also, simplify \sqrt{a^2}. The square root of a^2 is 'a'. Now, we have:

5 * a

Therefore, the simplified form of \sqrt{25a^2} is 5a.
