The diameter of a sphere is 6ft 6in. Find the radius
storchak [24]

<u>Answer: </u>

The diameter of a sphere is 6ft 6in. The radius of sphere is 3 feet 3 inches.

<u>Solution: </u>

Given that the diameter of sphere is 6 feet 6 inches.  

We have to find the radius of the sphere.

The relation between diameter and radius of sphere is given as  

\text { diameter }=2 \times \text {radius}

Therefore, radius=\frac{\text {diameter}}{2}

radius=\frac{6 \text { feet } 6 \text { inches }}{2}

Radius = 3 feet 3 inches.

Hence the radius of the sphere is 3 feet 3 inches.

Hey yall, who wants a quick 20?
aliya0001 [1]

Answer:

1) 8x

2) 12x - 3y

Step-by-step explanation:

1) Both of them have a like term, so you can subtract them across

2) 10x + 2x = 12x, have a like term so you can add them across and 3y is the outlier so that stays alone.

Hope this helps!

The outside of a picture frame measures 14 in and 20 in 196in^2 of the picture shows find the thickness of the frame
LuckyWell [14K]
The described picture frame can be visualized into two separate parts. The first area is equal to the area using the outermost dimensions for the length and width. 
             Area = Length x Height
              Area = (20 in) x (14 in) 
              Area = 280 in²

We are given that the area is only equal to 192 in². We subtract this value from the computed area.
         Difference = 280 in² - 192 in²
               difference = 88 in²

This area is equal to the area of the hollow space inside the frame. That is equal to,
      height = 20 in - 2x
      length = 14 in - 2x

The area,
               88 = (20 - 2x)(14 - 2x)

Simplify the right hand side of the equation.
             88 = 280 - 68x + 4x²

Divide the equation by 4,
            22 = 70 - 17x + x²

Transposing,
                x² - 17x - 48 = 0
The factors of the equation is 58.2. 

Thus, the thickenss is equal to 58.2 in

Plz help ill give u brainlist
adoni [48]
The problem tells you that a circle with radius 21 inches is painted in two colors. The two colors cover equal areas, so each color is half the area of the circle. You need to find half of the area of the circle. To do that, use the formula for the area of a circle, and then divide by 2.

A = \pi r^2

A = 3.14 \times 21~ inches \times 21~inches

A = 1384.74~square ~inches

Half the circle has area 1384.74 square inches / 2 = 692.37 square inches.

Answer: Each color covers 692.37 square inches.
