Answer:
- 150.72 cm³
- 314 cm³
- 160 cm³
- 48 cm³
Step-by-step explanation:
Put the given numbers in the relevant formula and do the arithmetic.
<u>right cylinder</u>
V = πr²h = 3.14(4 cm)²(3 cm) = 3.14×48 cm³ = 150.72 cm³
<u>cone</u>
V = 1/3πr²h = 1/3(3.14)(5 cm)²(12 cm) = 3.14×100 cm³ = 314 cm³
<u>pyramid of unknown shape</u>
V = 1/3Bh = 1/3(16 cm²)(30 cm) = 160 cm³
<u>square pyramid</u>
V = 1/3s²h = 1/3(3 cm)²(16 cm) = 48 cm³
The answer is 25/18
i got this by turning 1 2/3 into a mixed fraction and then multiplying it by 5/6
hi
not sure of the first line, but I assume you meant
A = ( 3 +3/4) / ( 4+1/2)
then we have : ( 12/4 +3/4) / ( 8/2 +1/2)
15/4 / 9/2
As divising by a number is equal to multiply by it's inverse , then inverse of 9/2 is 2/9 we have :
15/4 * 2/9
As you know, multiplying fraction means multiplty numerator with numerator and denominator with denominator
so : 15/4 * 2/9 = ( 15* 2 ) / ( 4*9) = ( 5*3 *2 ) / (2*2*3*3 ) = 5 / 6
Result is 5/6
The equation is very easy to solve since there is a quadratic formula that we can apply in the problem.
With the given equation 5w2+10w=40, we can arrange the problem into 5w2+10w-40=0.
a=5, b=10, c=-40
By applying quadratic formula, the answers are 2 and -4.
Answer:
100 minimum
