Answer:
19.74 inches
Step-by-step explanation:
Given as
Circumference of wheel = 62 inches
AS we know that Circumference (C) = 2×
×R
where R is Radius of circle
so, C = 2 × 3.14 × R
or, 62 = 2 × 3.14 × R
or 62 = 6.28 × R
so, Radius (R) = 
R = 9.872
Now Diameter = 2 × Radius
so, D = 2 × 9.872
Diameter = 19.74 inches Answer
Answer:
45c with an exponent of 3
Step-by-step explanation:
This is my very own step-step solution:
Step 1:
<span>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : </span>
<span> 42*x^5*y^4-((-7*x^3*y)*(b))=0
</span>
Step 2:<span>Equation at the end of step 1 :</span><span>
((42•(x5))•(y4))-((0-(7x3•y))•b) = 0
</span>
Step 3:Pulling out like terms :
<span> 42x5y4 + 7x3yb</span> = <span> 7x3y • (6x2y3 + b)</span>
The correct is: 7x3y • (6x2y3 + b) = 0 <span>
</span>
Quick Side Note:
<span>Binomial can not be factored as the difference of two perfect cubes
</span>
I hope this helps a little!
Hope you have a great day!
Answer:
Step-by-step explanation:
The idea here is to find the area of the circle and then subtract from it the area of the triangle. That will give you the area of what's left in the circle (the shaded part). The area of a circle is:
so
where 12.4 is the radius.
rounded to the nearest tenth. I used 3.14 for pi.
Now for the area of the triangle. The formula is
where h is the height of 12.4 and the base is the diameter which is 12.4 * 2 = 24.8
so

Now subtract the triangle's area from the circle's area:
482.81 - 153.76 = 329.05 mm²
