Answer:
tsa of semi-cylinder is 21.21m²
Step-by-step explanation:
tsa of cylinder = 2πr² + 2πrh
radius = diameter ÷2
= 1.5m
tsa = (2×π×1.5²) + (2×π×1.5×3)
= 4.5π + 9π
= 13.5π
≈ 42.412m²(3d.p) (cylinder)
semi = 42.41 ÷ 2
≈ 21.21m² (2d.p)
(Correct me if i am wrong)
Answer:
Step-by-step explanation:
you take 30% and 10% and turn them into decimal like so:
30/100=0.3
10/100=0.1
400.00(0.3)=120.00
120(0.1)=12
Answer:
x= 16 ft.
Step-by-step explanation:
Let 'x' and 'y' are the lengths of the two pieces then:
1.) x + y = 36
2.) x : y = 4 : 5 cross multiply
3.) 5x = 4y
by solving the system of equations
x + y = 36
5x = 4y
we find
x = 16 ft
y = 20 ft
