What is the volume of a hemisphere that has a diameter of 12.6 cm, to the nearest tenth of a cubic centimeter?

Mathematics

Volume of a sphere = 4/3 pi r^3
A hemisphere is half a sphere so 1/2*4/3 pi r^3 = 2/3 pi r^3
Given diameter = 12.6 but we need radius so diameter /2 or 12.6/2 r=6.3
2/3*pi*6.3^3 =
2/3*pi*250.047
166.698*pi
= 523.7

What two measurement could make up a complementary angle when one angle is 8 degrees more than the other?
Firdavs [7]
Complimentary angles add up to 90 degrees

x + y = 90
x = y + 8

y + 8 + y = 90
2y + 8 = 90
2y = 90 - 8
2y = 82
y = 82/2
y = 41

x = y + 8
x = 41 + 8
x = 49

so ur angles are : 41 and 49

Explain how to solve 2^(x + 1) = 9 using the change of base formula log base b of y equals log y over log b. Include the solutio
TEA [102]

Answer:

<h3>x = 2log₂(3) - 1</h3>

Step-by-step explanation:

2ˣ⁺¹ = 9

x+1 = log₂(9)

x+1 = log₂(3²)

Transfer the power value inside the bracket and put it before the log.

x+1 = 2log₂(3)

<h3>x = 2log₂(3) - 1 </h3>
