Step-by-step explanation:
1. radius=13in
diameter= 2r =2(13)=26in
area=πr²= 22/7*(13)²
531.14in²
circumference= 2πr=2*22/7*13
81.71in
2.radius=32ft
diameter= 2r =2(32)=64ft
area=πr²= 22/7*(32)²
3218.28ft²
circumference= 2πr=2*22/7*32
201.14ft
Answer:
60degrees
Step-by-step explanation:
For similar triangles, the angles of their angles are equal to matter the size.
Hence if triangle TRS is similar to triangle TMN, then;
<R = <M and <S = <N
Given that;
<T = 40 degrees
<R = 60degrees
<S = 80 degrees
Since <R = <M, then <M = 60degrees
the formula for area of a rectangle is
Area = length x width
since both the length and the width of the rectangle lie on the same x and y axis, we can find the distance between the width and the distance between the length by subtracting
(-4,9) (-4,-3)
these points lie on the same x axis, so they create a vertical line
9-(-3) = 12
12 units is the distance between them
(-4,-3) (-1,-3)
these points lie on the same y axis, so they create a horizontal line
-1-(-4) = 3
3 units is the distance between them
now that we have the length and the width, we can find the area
A = 12 x 3
A = 36 units²
