The radius of the circle expressed as a mixed number is:
inches.
<h3>What is the Radius of a Circle?</h3>
Radius of a circle = half the measure of the diameter of a circle.
Given:
diameter of a circle =
inches
Therefore:
Radius of the circle = 1/2(
)
= 1/2(47/6)
= (1 × 47)/(2 × 6)
= 47/12
=
inches.
Therefore, the radius of the circle expressed as a mixed number is:
inches.

D. The elevator takes 37.5 seconds to move down to the lobby.
8x+y=300
y= 300-8x
y= 300 - 8 (37.5)
y = 300-300
y = 0
wheb y =0 that means that the height is 0
No, because, using the Pythagorean Theorum:
6^2+8^2=9^2
36+64 IS NOT = TO 81
You need this key result: in any polygon, the sum of the interior angles is

where
is the number of sides of the polygon.
Your polygon has seven sides, and the measures of all angles are given. So, we can write

Again, we've simply written that the sum of all interior angles is the number of sides, minus two, times 180.
We can simplify both sides: we sum like terms on the left hand side, and we easily compute the right hand side:

and we can solve this equation for
by dividing both sides by 30:

Finally, the required angles is
