The area of the two trianglular ends is
.. (18 cm)*(40 cm) = 720 cm²

The perimeter of the triangular end is
.. 2*41 cm +18 cm = 100 cm
so the lateral area is
.. (100 cm)*(46 cm) = 4600 cm²

The total surface area is the sum of the end area and the lateral area.
.. 720 cm² +4600 cm² = 5320 cm²

$363.9ft^{2}$

Step-by-step explanation:

$Area =\pi r^{2} -\frac{1}{3}\pi r^{2} +\frac{1}{2}r^{2}sin\alpha \\\\\\ = \frac{2}{3}\pi 12^{2} +\frac{1}{2}12^{2}sin120 =363.9ft^{2}$

How are fractions and decimals related?

Savatey [412]

Fractions and decimals are related in a very close way. Ways such as they are both representing a whole number.

for example

1/2 , 0.5 , 50%

all three numbers have the same value but are expressed in a different format. all three represent the same whole number.

another example would be

1/4 , 0.25 , 25%

hopefully this helped. and or makes sense.

What is 424.12 rounded to the nearest 10th<br> ASAP

evablogger [386]

424.1

the nearest 10th refers to the first decimal place therefore there would only need to be 1 decimal place. and you don’t the round the 1 up when dropping the 2 because the 2 is less than five.

Samantha is making flower arrangements. She has 32 roses and 96 daisies. If she wants to make all the arrangements identical and

-Dominant- [34]

Answer:

3 daisies.

Step-by-step explanation:

Given that,

Samantha has 32 roses and 96 daisies.

She wants to make all the arrangements identical and have no flowers left over. We need to find the no of daisies in each flower arrangement.

For this, we need to first find the HCF of 32 and 96.

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

HCF = 32

No of daisies = 96/32 = 3

Hence, there are 3 daisies in each flower arrangement.
