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: 22 hours 28 minutes
Step-by-step explanation: 0843 means 8:43am and 0711 means 7:11am military time. In that order there is 22 hours 28 minutes from 8:43am today to 7:11 am tomorrow. The question itself is rather confusing so if this is not what you meant please let me know and I will re-do it.
Then,
3^y = 7, is equivalent to y = log_3(7)
We need to find which graph goes like log_3(x). For x =3, log_3(3) = 1, for x = 9, lo_3(9)=2, so .....
The first one!

.Answer:
3.65
Step-by-step explanation:
if 6 apples = $1.99, if you divide $1.99 by 6, you get the cost for one, then if you multiply that by 11, you get the amount for 11 apples. The real total is $3.64833333333 but if you round it, it goes to $3.65
