Answer:
70
Step-by-step explanation:
RU=20 (45-45-90 triangle)
use pythagorean theorum
20^2+b^2=73^2
evaluate
b^2=4929
sq root both side
rounded to nearest integer, side SU is 70
a quarter of a circle is 19.625
so the area of full circle is 19.625 x 4 = 78.5 sq. km
area of a circle is PI x r^2
78.5 = 3.14 x r^2
78.5/3.14 = 25 = r^2
r = sqrt(25) = 5
radius is 5 km
circumference ( perimeter) = 2 x PI x r
2 x 3.14 x 5 = 31.4 km
perimeter is 31.4 km
Answer:
190 cm2.
Step-by-step explanation:
First you have to find the area of the whole shape.
20 cm times 10 cm is 200 cm2.
Now, you have to find the area of the smaller shape inside.
5 cm times 2 cm = 10 cm2.
Finally, you subtract the area of the smaller shape from the larger shape to find the area of the shaded area.
200 cm2 - 10 cm2 = 190 cm2.
