Use the formula for area of a triangle:
Area = 1/2 x base x height.
Fill in what you know:
40 = 1/2 x 20 x height
Multiply both sides by 2:
80 = 20 x height
Divide both sides by 20
Height = 4 m

19.95
Step-by-step explanation:
if you take 1.05 times it by 19 you get your answer
Answer:
I think Yukari Yakumo or Sakuya
Step-by-step explanation:
We know that
surface area of sphere=4*pi*r²
r=√[surface area/(4*pi)]
for surface area=200.96 cm²
so
r=√[200.96/(4*pi)]------> r=4 cm
volume of a sphere=(4/3)*pi*r³-----> (4/3)*pi*4³----> 268.08 cm³
the answer is
<span>the approximate volume of the sphere is 268.08 cm</span>³
d)72 is the answer. It might also be c)48 but im not sure.
