<span>To find the original dimensions, write a proportion with the scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve. To find new dimensions, write a proportion with the new scale as the first ratio and the scale dimension compared to the actual dimension as the second ratio. Use cross products to solve.</span>
Answer:
A. 36
Step-by-step explanation:
The formula to find the area of a triangle is , where b is the base and h is the height. Since 12 is the base, and 6 is the height, we can find that the area of the triangle is:
= 36 sq. inches

Given:
The diameter of a sphere is 19 cm.
To find:
The volume of the sphere.
Solution:
We have,
The volume of the sphere is
where, r is radius.
Putting in the above formula.
Therefore, the volume of the sphere is 3592.8 sq. cm.
Less than. Because one of the numbers multiplying to make the product is lower than that of the other equation. 7.69*5=38.45 whereas 8*5=40
