Answer:

step by step

Step-by-step explanation:

where

r = radius

h= height

Area of a cylinder = 2πrh+2πr^2

Area of a cylinder = 2π8(3)+2π8^2

Area of a cylinder = 176π = 552.92

Area of a hemisphere= 3r2π

Area of a hemisphere= 3(2)2π

Area of a hemisphere= 12π = 37.699111843

Area of the cylinder in this problem

176π - 12π = 164π

By definition, the determinant equals ad - bc. What is the value of when x = -2 and y = 3? I NEED HELP PLEASE

sergiy2304 [10]

Answer:

Step-by-step explanation:

Taking the determinant of the matrices we will have;

= 4x(5y) - 2x(3y)

= 20xy - 6xy

= 14xy

Given x = -2 and y = 3

Determinant = 14(-2)(3)

Determinant = -28*3

Determinant = -84

What is the slope given: (5,2)&(9,-6)

Paul [167]

Answer:

The slope is -2

Step-by-step explanation:

To find the slope we do y2 - y1 / x2 - x1 or in this case, -6 - 2 / 9 - 5

Next, u solve -6 - 2 = -8 and 9 - 5 = 4

So we get -8/4 or simplified -2/1 or -2

The slope is -2

Hope that helps u! :)

In circle p, td¯¯¯¯¯ and tb¯¯¯¯¯ intersect at t. ta=10, tc=8, cd=12, and ab=x+2. find ab. circle p. answer

inysia [295]

The answer is AB = 6.

External value x (external value + internal value) =
External value x (external value + internal value) of the other side

Substitute, transpose, and simplify.

TA x (TA + AB) = TC x (TC + CD)
10 x (10 + (x + 2)) = 8 x (8 + 12)
120 + 10x = 160
10x = 40
x = 4

To find AB: x + 12; x = 4
AB = x + 2
AB = 4 + 2
AB = 6
