3 Hundredths + 3 tenths = ______

Answer:

3 Hundredths+ 3 tenths= 0.33.

Place value of the place immediately after the decimal point (i.e. tenth place) is 1/10, that of next place (i.e. hundredths place) is 1/100 and so on.

3 Hundredths is written as= 3 x (1/100)

= 0.03

3 tenths are written as= 3 x (1/10)

= 0.3

Then sum of 3 Hundredths, 3 tenths= 0.03 + 0.3

= 0.33

"hello students welcome to later q a
video session
i am sav your math tutor and question
for today is
the dome of a building is in the form of
a hemisphere
its radius is 63 decimeter
find the cost of painting at the rate of
rupees 2
per square meter
now radius of the hemispherical dome is
given that is 63 decimeter
or this can be written as 6.3 meters
so as the radius is given we have to
find
first of all the inner surface area of
the hemispherical dome
to find the inner surface area of the
hemispherical dome
because we are going to paint that so
here
inner surface area of the hemispherical
dome can be given by
formula which is 2 pi r square
and that is equal to 2 into 3.14
into r square that is 6.3
whole square
so your answer comes out to be 249.48
and that is meter square
now here the inner surface area of the
dome
we have got that is 249.48 meter square
now one one meter square cost is given
that is rupees two
cost of painting
1 meter square which is equal to rupees
2 so what will be the cost of painting
to 49.48 meter square
that is asked in the question
and that will be equal to 249.4
multiplied by 2 so it will give you
498.96
rupees
so finally therefore
cost of painting is
498.96 rupees
that is our final answer if you have any
doubt regarding this
you can post it in our comment section
