What is the value of r?
r= 4 ft
r= 8 ft
r = 16 ft
r = 32 ft

What Is The Value Of R?r= 4 Ftr= 8 Ftr = 16 Ftr = 32 Ft

Answers

Answer 1

R=8ft

Step-by-step explanation:

Calculate r using the given formula

r = , with Area = 64π

r = ← cancel π on numerator/ denominator

r = = 8

Answer 2

The required value of radius of circle r is 8 ft

From Figure the area of circle is = 64π, we have to find the radius of the circle.

What is area of circle?

Area of the circle is = π[tex]r^2[/tex]

since

the area of the circle is given = 64π

And,
Radius = √area/π
radius= √64π/π
Radius = √64
Radius = 8 ft

Thus The required value of radius of circle r is 8 ft.

Bill's new porch is rectangular, with an area of 50 square feet. If the length of the porch is two times the width, what is the perimeter of the porch?
A.30
B.40
C.50
D.60

Answers

the answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.

Is -6 a solution for the equation 3(2x - 8)= -4(-6 +21)?

Answers

Answer:

YeS, it is a solution

Step-by-step explanation:

Here, we want to check if -6 is a solution to the question

What we have to do is to replace x by -6

If what we have on the left equals that on the right, then -6 is a solution

Thus, we have it that;

3(2(-6) -8)

= 3(-12-8)

= 3(-20) = -60

for the right hand side

-4 (15) = -60

This means both sides are equal and that -6 is a solution

two times the sum of a number and 18 is at least -21

Answers

Answer:

2x + 18 ≥ 21

x ≥ 2/3

Step-by-step explanation:

Let sum be X

2 times the sum means 2x

the sum of a number and 18 means x + 18

at least -21 means ≥ 21

put them together, and you get, 2x + 18 ≥ 21

If solving for x,

2x + 18 ≥ 21

2x ≥ 3

x ≥ 2/3
