Answer:
First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
Answer:
the answer to - 2/5 -4/5 + - 9/10 is -2.1
Answer:
231
Step-by-step explanation:
<u>Given</u>:
Given that the radius of the hemisphere is 9.8 inches.
We need to determine the volume of the hemisphere.
<u>Volume of the hemisphere:</u>
The volume of the hemisphere can be determined using the formula,

where r is the radius of the hemisphere.
Substituting r = 9.8 in the above formula, we get;

Simplifying, we get;



Rounding off to the nearest tenth, we get;

Thus, the volume of the hemisphere is 1970.2 cubic inches.
