Answer:
BA = 25π,
LA = 25√2π,
TA = 25π + 25√2π,
V = 41 and 2 / 3π
Step-by-step explanation:
We need to determine the height here, as it is not given, and is quite important to us. The height is a perpendicular line segment to the radius, hence forming a 45 - 45 - 90 degree triangle as you can see. Therefore, by " Converse to Base Angles Theorem " the height should be equal in length to the radius,
( Height = 5 inches = Radius
______
Now knowing the height, let's begin by calculating the base area. By it's name, we have to find the area of the base. As it is a circle, let us apply the formula " πr^2 "
- Base Area = 25π
______
The lateral area is simply the surface area excluding the base area, the surface area having a formula of " πr^2 + πrl. " Thus, the lateral area can be calculated through the formula " πrl, " but as we are not given the slant height ( l ) we have to use another formula, -
- Lateral Area = 25√2π
______
And the surface area is the base area + lateral area -
- Surface Area
______
The volume of a cone is 1 / 3rd that of a cylinder, with a simple formula of Base * height. Therefore, we can conclude the following -
- Volume = 41 and 2 / 3π
Answer:
i think it is Move the decimal after the number 1.
Step-by-step explanation:
it the text it says
"To convert our example, 602,200,000,000,000,000,000,000, into a scientific notation, <em>the first step is to place a decimal after the digit 6</em>, and then drop all the zeros after the 2. This will leave us with a coefficient of 6.022. Next, to find the exponent, count the number of times you had to move the decimal point until it landed after the first digit of the coefficient. The answer is 23; therefore, the scientific notation is 6.022 x 1023. In cases where the numbers are multiples of 10, only the base number 10 and the exponent can be used. For instance, the number 1,000,000,000, can be written as 109. Now you try it. What is the scientific notation for a light year, which has been estimated at 9,500,000,000,000 km? As you read the information in this lesson, challenge yourself by converting the large numbers into scientific notations."
216. All you have to do to find volume is to multiply the numbers. 12 x 18 = 216.
Answer:
(x -+2)² + (y - 4)² = 36
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 2, 4) and r = 6 , then
(x - (- 2))² + (y - 4)² = 6² , that is
(x + 2)² + (y - 4)² = 36 ← equation of circle
