What is the volume of a hemisphere with a radius of 9.8in, rounded to the nearest tenth of a cubic inch?
Fofino [41]

<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,

V=\frac{2}{3} \pi r^3

where r is the radius of the hemisphere.

Substituting r = 9.8 in the above formula, we get;

V=\frac{2}{3} (3.14)(9.8)^3

Simplifying, we get;

V=\frac{2}{3} (3.14)(941.192)

V=\frac{5910.69}{3}

V=1970.23

Rounding off to the nearest tenth, we get;

V=1970.2 \ in^3

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

For the piecewise function, find the values g(-1), g(2), and g(5). g(x)= x+4, for x≤2 9-x, for x&gt;2​
Lelechka [254]

Answer:

g(-1) = 3, g(2) = 6, g(5) = 4

Step-by-step explanation:

Please refer to attached photo. (Apologies for the terrible handwriting.)

From here we can see,

g(x) = x + 4 applies for values x less than or equal to 2.

g(x) = 9 - x applies for values x more than 2 (which does not include 2.)

g(-1):

Since -1 < 2,

g(-1) = -1 + 4 = 3

g(2) = 2 + 4 = 6

g(5):

Since 5 > 2,

g(5) = 9 - 5 = 4
