Answer:
the larger cyclinder has a surface area which is 9 times the surface area of the smaller cyclinder.
Step-by-step explanation:
Surface area of larger cyclinder
Radius = 6cm
Height = 18cm
A = 2πrh + 2πr^2
= 2*3.14*6*18 + 2*3.14*6^2
= 678.24 + 226.08
= 904.32 cm
Smaller cyclinder (1/3 of the larger cyclinder)
Radius = 2cm
Height = 6cm
A = 2πrh + 2πr^2
= 2*3.14*2*6 + 2*3.14*2^2
= 75.36 + 25.12
= 100.48 cm
Comparing the surface area of the larger cyclinder and the smaller cyclinder
= 904.32 cm / 100.48 cm
= 9
This means, the larger cyclinder has a surface area which is 9 times the surface area of the smaller cyclinder.
Answer:
Step-by-step explanation:
Given:
E is the midpoint of segment AC.
AE ≅ EC
∠BAE ≅ ∠ECD
To prove:
ΔAEB ≅ ΔCED
Statements Reasons
1). AE ≅ EC 1). Given
2). ∠BAE ≅ ∠ECD 2). Given
3). ∠AEB ≅ ∠CED 3). Vertically opposite angles theorem
4). ΔAEB ≅ ΔCED 4). By ASA postulate of congruence
-108=8x
Divide 8 on both sides
-13.5=x
The answer is...X=-13.5

Answer:
782 in
Step-by-step explanation:
To find the length of fence, we have to find the perimeter first.
Given
Length = l = 25 feet 8 in
Width = w = 8 feet 8 in
Opening = o =3 feet 6 in
So,
we have to convert the lengths into same unit first
So,
l = (25*12)+8 = 308 in
w = ( 8*12) +8 = 104 in
O = (12*3) + 6 = 42 in
Perimeter = 2(l+w)
= 2(308+104)
=2(412)
=824
As the opening does not need fencing
Total fence = P - o
= 824 - 42
=782 in
or
65 feet 2 in ..
