12 + r = 3 how do i solve this?

2 answers:

5 0

You’d have to try to get r on one side of the equation.
You can do that by subtracting 12 from both sides which would make it so
R = -9

Find the volume of a cylinder below . The formula for the volume of a cylinder is . The radius of the circle is represented by r

lapo4ka [179]

Answer:

The volume of the cylinder V = 942 cm³

Step-by-step explanation:

Step(i):-

Given that the graph

The height of the cylinder (h) = 12cm

The diameter of the cylinder d = 10cm

The radius of the cylinder

d = 2r

r = $\frac{10}{2}$

r = 5 cm

Step(ii):-

The Volume of the cylinder

V = π r² h

V = π (5)²(12)

V = 300π cubic centimeter

V = 300 × 3.14

V = 942 cm³

Final answer:-

Volume of the cylinder V = 942 cm³

Factor each trinomial completely. 4x^2 - 25b^2 and x^2 - 81

GenaCL600 [577]

Step-by-step explanation:

4x2 - 25b2

We can solve it by the squares so

(2x - 5b) (2x + 5b)

2) x2 - 81

The same case is here so

(x - 9) (x + 9)

In the figure above, square ABCD and triangle EFG have the same areas. If AB =6 and EG =8, what is the height o triangle EFG?

lawyer [7]

Answer:

The height of triangle EFG is 9 units

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the area of a square ABCD

The area of a square is equal to

$A=b^2$

where

b is the length side of the square

we have

$b=AB=6\ units$

substitute

$A=6^2=36\ units^2$

step 2

Find the height of triangle EFG

The area of triangle EFG is equal to

$A=\frac{1}{2}(b)(h)$

where

b is the base of triangle

h is the height of triangle

we have

$b=EG=8\ units$

$A=36\ units^2$ ---> area of triangle EFG is the same that the area of square ABCD

substitute the given values in the formula

$36=\frac{1}{2}(8)(h)$

solve for h

$36=4h\\h=9\ units$

therefore

The height of triangle EFG is 9 units
