Answer:
2002.77mm³
Step-by-step explanation:
Formula : pi × r²× height
pi × 5² × 25.5 = pi × 25 × 25.5 = 2002.765317mm³
Answer:
EF=3
FG= 9
Mark Brainliest pls
Follow me pls
Hope it helps mate.
Step-by-step explanation:
<em><u>Given</u></em> - EG=12
EF=2x-3
FG = x+6
<em><u>Solution</u></em><em><u>-</u></em>
We know that EG= EF+FG
putting given values
12= 2x-3 +x+6
3x+3=12
3x=9
x =3
EF=2x-3 = 2×3-3 = 3
FG = x+6 = 3+6 = 9
Suppose A equals 10. Lets use 20% of 10, or 2.
10/2 = 5.
As we can see, the equations varies depending on the percentage used. We can effectively conclude that:
A/(1/5A)
5A.
The equation is equal to the reciprocal percentage times A.
Another example:
50 divided by 10% of 50 (5).
50/5 = A
50 * 1/5 = A
10 = A
Answer:
I don't know what I'm suppose to solve, but it's probably one of these.
x = 8
Angle A = 48 degrees, Angle B = 132 degrees
Step-by-step explanation:
(4x + 12) + (15x - 3) = 180
19x +9 = 180
19x = 171
x = 9
Angle A: 4x + 12 --> 4(9) + 12 --> 36 + 12 --> <em>48</em>
Angle B: 15x - 3 --> 15(9) - 3 --> 135 - 3 --> <em>132</em>
48 + 132 = 180
