Hello there!
Surface Area = 4pir^2
First, we need to find our radius, since we have our diameter all we need to do is divide it by 2. That means, 10 divided by 2 equals 5.
Our radius is 5.
Now, we can plug it into the formula.
4(3.14)(5^2)
4(3.14)(25)
4(78.5)
4(78.5) = 314
Now, convert into pi.
314 = 100pi or 100Π
Since the area formula is pi times radius to the second power, then just plug in the things you know. for ex: The area is 314, then work backwards and divide 314 by pi which equals 100 then unsquare it which is 10 because 10*10=100. So the radius is 10
Answer:
(3.5 , 3.5)
Step-by-step explanation:
Midpoint formula is x1+x2/2 and y1+y2/2
7 + 0/2 and 9 + (-2)/2
7/2 simplifies to 3.5
7/2 again simplifies to 3.5
so the midpoint coordinate is
(3.5,3.5)
Answer:
Rewrite as an equation.
log
9(729)=x
Rewrite
log
9(729)=x
in exponential form using the definition of a logarithm. If
x and b
are positive real numbers and b
does not equal 1, then log b(x)=y is equivalent to by=x. 9x=729
Create expressions in the equation that all have equal bases.
(32)x=3
Rewrite
(32)x as 32x. 32x=36
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
2 x 3=6
Solve for
x.x=3
The variable x
is equal to
3.3
Step-by-step explanation:
To solve this problem, find the area of the rectangle and the two triangles:
Rectangle:
11 x 12 = 132
Triangles:
17 - 11 = 6;
6 ÷ 2 = 3;
3 x 12 = 36;
36 x 2 = 72
Total Area:
132 + 72 = 204
Your answer would be 204 ft².
