It’s wrong.
The surface area means the area of the outside of the cube.
The area of a square is just width x height. And we are told one of the sides is 5.
A square has all equal sides. So what’s 5x5? then times that by the number of squares
I’ll put the answer in the comments
Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is the radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.
Answer:
14.5 i think
Step-by-step explanation:
2.5 + 12 = 14.5
25c(quarters) x 12 = $3.00
If theres 28 coins, and 12 are quarters, then that means theres 16 coins left to use for dimes.
10c(dimes) x 16 = $1.60
$3.00 + $1.60 = $4.60
Therefore, there are 12 quarters and 16 dimes.
Hope this helps! Feel free to ask any questions.
Answer:
150x^2+2340x-50000
Step-by-step explanation:
5[6x(5x+78)-10000]
5[30x^2+468x-10000]
150x^2+2340x-50000
