<span>its diameter is 16 inches,
</span><span>So, according to the Pythagorean Theorem, for some right triangle with legs of length a, b, and hypotenuse of length c,
then a² + b² = c²
</span>c = 16 inches, and a = b.
<span>a² + a² = 16² </span>
<span>2a² = 256 </span>
<span>a² = 128 </span>
<span>√a² = √128 </span>
<span>a = √128 </span>
<span>a = √(64•2) </span>
<span>a = 8√2 </span>
<span>So, the size is an 8√2 by 8√2 square. </span>
Answer:
2.25π in²
Step-by-step explanation:
The area can be found from the circumference using the formula ...
A = C²/(4π)
Putting in the given dimension, you have ...
A = (3π)²/(4π) = (9/4)π = 2.25 π . . . . in²
To find the area of the triangle, use the area of a triangle formula: Area= 1/2(base)(height). In this image, the base of the triangle is 5.9. The height is 6.8. To find this, you multiply 1/2*6.8*5.9 which will give you answer: 20.06
