Circumference of a circle: 2 * Pi * R
1. Calculate radius from diameter.
Radius = Diameter/2
Radius = 15/2
Radius = 7.5cm
Formula to calculate the circumference:
2 * Pi * R
= 2 * Pi * 7.5
= 15 * Pi
= About 47.10 cm in terms of Pi.
So, in conclusion, the circumference if this circle is about: 47.10cm.
Answer:
22.25
Step-by-step explanation:
take the two values away
the sector is the full address , the triangle is in it. the segment is the bit left near the circumference
Answer:
![\sqrt[15]{x^7}](https://tex.z-dn.net/?f=%5Csqrt%5B15%5D%7Bx%5E7%7D)
Step-by-step explanation:
If we have the expression
, we have to think about exponent rules.
If we have
, then the value will be equal to
.
So
simplified will be 
Converting
and
into fifteenths (lcm) gets us
.
We can convert
into a radical by taking the denominator root of x to the numerator.
.
Hope this helped!
D) 3x+6
x + 1 + 2x +5
That will = D
