Answer:
ans 3
Step-by-step explanation:
Circumference is distance round a figure. When diameter is trippled, the circumference will also tripple.
Here is a proof
Take the moon to have circular shape and has diameter d
Circumference is given by C=πd
When the new diameter is trippled, diameter will be 3d and the new circumference will be
C=π3d=3πd
Evidently, the new circumference is three times the original circumference. Therefore, for this case, the new circumference will be 3 times the original
We know that
length of circumference=2*pi*r
for r=18 cm
length of circumference=2*pi*18--------> 36pi cm
if 2pi radians (full circle)------------------> has a length of 36pi cm
(3/2)pi radians---------------------------> X
X=(3/2)pi*36pi/2pi----------> x=27pi cm
the answer is
27pi cm
Answer:
and
Step-by-step explanation:
According to the figure, x is part of a complementary angle and y is from a supplementary angle:
Answer:
2 cups
Step-by-step explanation:
340.8 cm^2.
72+72+72+62.4+62.4=340.8cm^2.
