A suitable calculator will tell you that percentage is about
48.
Angle B is 36. Hope this helps. :)
576 sq. inches
divide 96 by 4 to get the length of each side then multiply that answer by itself
Answer:
(a)f(4) square cm.
(b)f(10.91)-f(10.9) Square centimeter.
Step-by-step explanation:
f(r)=the area of a circle (in square cm) that has a radius of r cm.
(a)Area (in square cm) of a circle whose radius is 4 cm.
Since r=4cm
Area of the circle = f(4) square cm.
(b) When the radius of the increases from 10.9 to 10.91 cm.
- Area of the circle with a radius of 10.91 = f(10.91) square cm.
- Area of the circle with a radius of 10.9 = f(10.9) square cm.
Change in the Area = f(10.91)-f(10.9) Square centimeter.
