Answer:
21 and 23
Step-by-step explanation:
So a circular pool will be in the shape of a cylinder. and the formula for finding the area of a cylinder is
. r=radius, h=height. If we put the numbers into the equation it is
.14 squared is 196 and 4*14= 56. So our equation is now
. 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(196)+6.283(56). Just multiply them. 1231.504+351.858= <span>
1583.362</span> is your final answer.
Given:ABCD is a rhombus.
To prove:DE congruent to BE.
In rombus, we know opposite angle are equal.
so, angle DCB = angle BAD
SINCE, ANGLE DCB= BAD
SO, In triangle DCA
angle DCA=angle DAC
similarly, In triangle ABC
angle BAC=angle BCA
since angle BCD=angle BAD
Therefore, angle DAC =angle CAB
so, opposite sides of equal angle are always equal.
so,sides DC=BC
Now, In triangle DEC and in triangle BEC
1. .DC=BC (from above)............(S)
2ANGLE CED=ANGLE CEB (DC=BC)....(A)
3.CE=CE (common sides)(S)
Therefore,DE is congruent to BE (from S.A.S axiom)
Answer:
f(x) = -x -1
Step-by-step explanation:
You can make the correct choice by seeing which equation works for the first line of the table.
f(-1) = -(-1) -1 = 0 . . . . . the first equation works
f(-1) = -(-1) +1 = 2 . . . not zero
f(-1) = -1 -1 = -2 . . . not zero
f(-1) = 1 -(-1) = 2 . . . not zero (same as second equation)
Answer:
58.25n+30p-2
Step-by-step explanation:
Given the expression as;
1 + 4.25n + 32p – 3 + (–2p) + 54n
collect like terms
1-3+4.25n+54n+32p-2p
-2+58.25n+30p
58.25n+30p-2
I have copied one brainly user's answer, sorry for that...
However, hope it helps you!!!
