Answer: 188.4 cm
Step-by-step explanation:
Given
the radius of the circle is
Also, circumference is given by
Putting values
The circumference of the circle is
X^2 + 16x + ?
a^2 + 2ab + b
(a + b)^2 which is a perfect square.
To find b to determine the last value, you divide 16x by 2x.
so:
b = 8
the last value would be 8^2 which is 64.
Hence answer is C - 64
The answer is 84 7/12
You would convert the mixed fractions to improper fractions then multiply the numerators and denominators. Then you convert your answer back into a mixed fraction.
7 1/4 is equal to 29/4
11 2/3 is equal to 35/3
29/4 • 35/3
So 29 • 35 = 1015 and 4 • 3 = 12
Now you have the improper fraction 1015/12, which is 84 7/12 as a mixed fraction in its simplest form.
Hoped this helped!
Answer:
a circle
Step-by-step explanation:
parallel to the base meaning that it has to be parallel to the circle on the bottom of the base. Picture yourself cutting the cone where the plane is and see what shape that is. It's a circle
