There are two solid hemispherical objects made of clay having the same shape and size. If the total surface area of one hemispherical object is 462 square cm, find the total surface area of the sphere which is formed by attaching those two hemispherical objects.​

Answers

Answer 1
radius=7,tsa of spheres is 616sq.cm

hemisphere = 462 square cm
Radius=7cm
Now,
TSA of sphere=4×22÷7×7×7
=616 sq.cm
Answer 2

The area of a 2D form is the amount of space within its perimeter. The total surface area of the formed figure is 615.75216 cm².

What is an area?

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Given that the total surface area of one hemispherical object is 462 square centimeters, therefore, we can write,

The total surface area of the hemisphere = 3πr²

462 cm² = 3πr²

r² = 462/(3π) cm²

r² = 49.0197 cm²

r = 7 cm

Now, when the two hemispheres will be attached, the total surface area of the formed figure will be equal to the total surface area of a sphere,

Therefore, we can write,

Total surface area = 4πr²

                              = 4 × π × (7 cm)²

                              = 615.75216 cm²

Hence, the total surface area of the formed figure is 615.75216 cm².

Answers

Answer:

Nancy’s Store

Step-by-step explanation:

To find which store has a better deal we are going to have to find the unit price per pen. To do this we do the following:

2.56/8 and 2.286 after doing both divisions we find that the cost of price per pens is .32$ from Nancy and .38$ from Joe.

i believe the answer is y = -2x+4
First find the slope.
Get 2 points and use the slope formula.
(0,4)(1,2)
2-4 / 1-0
-2 / -1 = 2
y = 2x + b
Now to find the y - intercept
The point where x is 0 and y is a number is your y - intercept. In this case it’s the first point. (0,4)
The equation in y=mx + b form would be....
y = 2x + 4

c + s = 12

or

11c + 15s = 148

where c is the number of new york cheese sold and s is the number of strawberry cheesecake sold

Step-by-step explanation:

We want to give one equation that we can get from the information above

Let the number of the new york cheese cake be c while the number of the strawberry cheese cake sold be s

A total 12 was sold:

So:

c + s = 12

Let’s now work with the prices;

11c + 15s = 148

Answer:

Step-by-step explanation:

To represent this illustration on the number line.

Mark your number line with positive values on the right side and negative values on the left side. On the number line, you will start with your negative number -2 then proceed to the positive side up to 5 times. On the integer tile, we would sum up 5 groups of negative 2 tiles or subtract 2 groups of 5 positive tiles.

The diagram below indicates the representation of the integer tiles and number line.

With integer tiles, you would add 5 groups of negative 2 tiles or remove 2 groups of 5 positive tiles. On the number line, you would bounce by 5 to the left 2 times.

Juan decided to start saving for college. He deposited $500 into an account which earns 4% simple annual interest. At the end of each year, he will add $250 to this account. How much will he have in his account after the end of three years?

Answers

Answer:

$5504

Step-by-step explanation:

Given that :

Principal amount = $500

Interest = 4% simple interest annually

Amount added at the end of each year :

First year:

Principal + (Principal * rate * time)

500 + (500 * 0.04) = 520

$520 + $250 = $770

2nd year:

770 + (770 * 0.04) = $800.80

$800.80 + $250 = 1050.80

3rd year:

1050.8 + (1050.8 * 4) = 5254

$5254 + 250 = $5504
