What is the volume of a hemisphere that

ch4aika [34]

Given:

Given that the diameter of the hemisphere is 12.6 cm

The radius of the hemisphere is given by

$r=\frac{d}{2}=\frac{12.6}{2}=6.3$

We need to determine the volume of the hemisphere.

Volume of the hemisphere:

Let us determine the volume of the hemisphere.

The volume of the hemisphere can be determined using the formula,

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

Substituting the values, r = 6.3 and π = 3.14, we have;

$V=\frac{2}{3} (3.14)(6.3)^3$

Simplifying the values, we have;

$V=\frac{2}{3} (3.14)(250.047)$

$V=\frac{1570.29516}{3}$

Dividing, we have;

$V=523.43172$

Rounding off to the nearest tenth, we get;

$V=523.4$

Thus, the volume of the hemisphere is 523.5 cm³

What is 3 quarters of 20?

Ulleksa [173]

Well, one quarter of 20 is 5 (because 20 ÷ 4 = 5). so, to find 3 quarters, we multiply 5 times 3.

5 × 3 = 15, so 3 quarters of 20 is 15.

Measure of Angle 1 is 5x. Measure of Angle 3 is x-24. What is the measure of Angle 1?

olga55 [171]

Answer:

The answer to your question is: 30°

Step-by-step explanation:

Data

m∠ 1 = 5x

m∠ 3 = x - 24

Process

m ∠ 1 = m ∠ 3 because they are vertical angles

5x = x - 24

5x - x = 24

4x = 24

x = 24 / 4

x = 6

Angle 1 = 5(6)

= 30°
