Answer:
-5
Step-by-step explanation:bro all u have to do is divide 8 by -43
We know that
scale factor=1 in/7.5 ft
scale factor=measurements on the blueprint/measurements <span> in the actual
</span>measurements on the blueprint=[measurements in the actual*scale factor]
so
for 18 ft
measurements on the blueprint=[18 ft*(1 in/7.5 ft)-----> 2.4 in
for 16 ft
measurements on the blueprint=[16 ft*(1 in/7.5 ft)-----> 2.1 in
the dimensions on the blueprint are
2.4 in x 2.1 in
A = pi * r^2.....r = radius and pi = 3.14
A = (3.14)(13^2)
A = 3.14(169)
A = 530.66
H=√d^2-w^2
=√146.4 1-92.16
=7.3 inches
the principle used here is pythagoras theorem
all the best.
620.25 u calculate 7443 and divide that by 12
