Answer:

306 mi^2

Step-by-step explanation:

surface area = area of base + lateral area

surface area = s^2 + 4bh/2

surface area = (10 mi)^2 + 4(10 mi)(10.3 mi)/2

surface area = 306 mi^2

The circle can be cut into pieces, separated, and fit together to form a parallelogram that has the same area. The height of the parallelogram is the radius and the base is half the circumference, which is r. The area is r(r), which is equal to r2.

A hard candy has a radius of 9 mm. The candy has a spherical soft center with a radius of 6 mm, with a hard shell surrounding it
goblinko [34]
Well you have to subtract the soft shell volume from the entire candy volume. Using the formula for the volume of a sphere, the whole candy is 4/3*729*3.14=3052.08
the soft center is 4/3*216*3.14= 904.32. If you subtract, you get the answer of 2147.76 mm^3.
