Answer:
314.16 in²
Step-by-step explanation:
The surface area of a sphere has a formula.
4πr²
Where r is the radius of the circle.
4π × 5²
4π × 25
100π
= 314.159265
Umm. Where is the question?
Answer is 18 do you need work shown
Answer:
the first answer is m<3=87
the second answer is m<4=44
Step-by-step explanation:
use the triangle theorem lol
but how i found out was angle 3 and what ever angle has 93⁰ are supplementary meaning that they equal 180⁰ so i subtracted 93⁰ from 180⁰ and got 87⁰ as tbe measure of angle 3
angle 4, 3 and the given angle, since it makes a triangle should equal 180⁰. so 180⁰- 49⁰-87⁰ leaves you with 44⁰
solution;
a) From the given information,
N = 53,min=42 and max = 129
K = 1+3.322log₁₀53
= 1+3.322(1.724)
= 1+5.728
= 6.728
Number of classes is 7.
b) find the width of the class interval first
width = max – min /classes
= 129-42/7
= 87/7 =12.42
Take the next largest number 13 as class width. Since the minimum value is 42
The lower limit iof the first class could be 40.
So,
The upper limit of the last class is,
40+(13 x 7) = 131
As the upper limit of the last class covers the entire range of values,
It is better to take the lower limit of the first class as 40
The lower limit of the first calss could be 40.
