Answer:
3rd group of possible answers is the correct set
Step-by-step explanation:
Each of the three points in the 3rd line of possible answers is a solution of the given equation, as can be verified by substitution:
If x = -2, y = -8(-2) = +16
If x = 3, y = -8(3) = -24
If x = -4, y = -8(-4) = +32
The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π
4
10) + ( π
4^2)
= 40π + 16π
= 56 π = 56
3.14
= 176 sq.units
Answer:
11 and 7
Step-by-step explanation:
let x be the bigger number and y the smaller
the sum of the two numbers is 18
x+y=18
x=18-y------i
the sum of the greater number and twice the smaller number is 25
x+2y=25----ii
substituting i in ii
18-y+2y=25
collecting like terms
y=25-18
y=7
subtitute for y in i to get x
x=18-y
x=18-7
x=11
