Answer:
half a sphere is called a hemisphere
Answer:
62°
Step-by-step explanation:
The angle R inscribes the arc FQ, so using the property of inscribed angles in a circle, we have that:
m∠R = mFQ / 2
The arc FQ is the sum of the arcs FP and PQ, so we have:
mFQ = mFP + mPQ = 11x + 7 + 60 = 11x + 67
Now, with the first equation, we have:
12x + 1 = (11x + 67) / 2
24x + 2 = 11x + 67
13x = 65
x = 5°
So we have that mFP = 11x + 7 = 55 + 7 = 62°
9^2 / 3(1)
81 / 3 =27
A is the answer
The answer is either 14.5 * 8 or 14.5 * 10 , because a decagon can have 8 triangles of unequal size or 10 triangles of equal size.
Answer: 16,503,616 leagues²
Step-by-step explanation:
Assume that the Earth is a sphere. Then, you need to use the formula for calculate the surface area of a sphere:
Where r is the radius.
Divide the diameter by 2 to calculate the radius of the Earth:
Substituting values into the formula , you get that the total surface of the Earth to the nearest whole number is:
