Given:
The radius of inner circle = 13 yd.
The width of the shaded region = 8 yd
To find the area of the shaded region.
Now,
The radius of the outer circle = 13+8 yd = 21 yd
Formula
The area of a circle of radius r unit is 
sq unit.
where, 
= The area of the shaded region
= Area of the outer region
= Area of the inner region
Now,
sq yd
And,
sq yd
Therefore,
sq yd
sq yd
Hence,
The area of the shaded region 854.08 sq yd.
Rounded to the nearest whole number is still 43
Step-by-step explanation:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
Answer:
Y=4x+4
Step-by-step explanation:
if it grows 4 inches each year that means it's the slope
and 4 feet tall model is the y intercept cuz its what you begin with
It should be the number 55. <span> ❤</span>please mark me as brainliest ❤
