Answer:
I am not sure, but I am sure that D is true
Step-by-step explanation:
The area of the entire circle is pi*(7)^2, or 49pi.
Due to the 90 degree angle, the area of the larger blue sector is
90
------- * 49 pi = 49/4 units^2
360
The area of the smaller blue sector is
48
------- 49 pi = (2/15)(49 pi) = 98 pi/15 units^2
360
The total area of the blue sectors is the sum of 98 pi/15 and 49 pi/4 (units^2):
59 units^2
Answer:
339.3 mi^2
Step-by-step explanation:
The formula for the surface area of a cylinder: 2pi*rh + 2pi*r^2
substitute the radius and height into this formula, and remember that radius is half of the diameter.
