The radius of a sphere is calculated through the equation,
V = 4πr³ / 3
where r is the radius. Substituting the radius given in the equation,
V = 4π x (3,760.4 miles)³ / 3 = 2.23 x 10^11 miles
Thus, the volume of the planet Venus is calculated to be 2.23 x 10^11 miles, approximately.
answer
z = 100
opposite angles
when inscribed in a circle, the opposite angles of a quadrilateral add up to 180
so z + 80 = 180 and y + 120 = 180
solve for z
z + 80 = 180
z = 180 - 80
z = 100
Answer:
25% decrease
Step-by-step explanation:
Take the original amount of books and subtract the new number of books
20 -15 = 5
Divide by the original amount of books
5/20 = .25
Multiply by 100%
25%
It is a decrease since the amount went down
25% decrease
