Answer:
175.1
Step-by-step explanation:
Find the area of the semicircle:
(pi • radius²) / 2. [Radius is half of diameter]
(3.14 • 4²) / 2
(3.14 • 16) / 2
(50.24) / 2
25.12
Find the area of the parallelogram:
(base • height)
(30 • 5)
150
Add the areas of both shapes to get total area
25.12 + 150 = 175.12, round to the nearest tenths, 175.1
Hope this helps!
Answer:
such strips of
can be cut and
would be left over.
Step-by-step explanation:
Given is
length of a wire.
We have to cut strips of 
If we factorize 
We get
full and
and 
Similarly , if we factorize 
We get full
and another
would be left.
Divide 36 by 45, then multiply the decimal by 100 to get the percent.
36 / 45 = 0.8
0.8 x 100 = 80
The answer is 80%
Regular pyramid
area of triangle=1/2bh
we find the areas of each
area of base=15.6
area of each outer triangle=1/2 times 6 times 7=21
3 of them
3*21=63
add them together
63+15.6=78.6
total area aka SA=78,6 ft^2
