Answer:

889.66 cm^3

Step-by-step explanation:

<em>here's</em><em> your</em><em> s</em><em>olution </em>

<em> </em><em> </em><em> </em>=> radius of cylinder = 5 cm

=> height of cylinder => 8 cm

=> radius of hemisphere = 5 cm

=> volume of toy = ( vol of cylinder + vol of hemisphere)

=> volume of cylinder = πr^2h

=> putting value , = 22/7*5*5*8

=> volume = 628 cm^3

=> volume of hemisphere = 2/3πr^3

=> putting value , = 2/3*22/7*5^3

=> volume of hemisphere = 261.66 cm^3

=> volume of toy = (628 + 261.66)cm^3

=> volume = 889.66 cm^3

hope it helps

the length of a rectangular garden is 3 m greater than the width. The area of the garden is 70m squared. find the dimensions of
Lerok [7]
A = l x w

so you know that the length is 3m longer than the width, so you could use a formula to represent that

w = l + 3

you then substitute the second equation into the first to solve for l

70 = l x (l +3)
70 = l^2 + 3l

you could then rearrange the formula and solve for l using the quadratic formula 

0 = l^2 + 3l - 70

l = -3 +- (square root (3)^2 - 4(1)(70)) / 2(1)
l = -3 +- (square root 9 + 280) / 2
l = -3 +- (square root 289) / 2
l = -3 +- 17 / 2

then you solve for the two seperate roots

l = -3 + 17 /2
l = 14 / 2
l = 7

or 

l = -3 - 17 / 2
l = -20 / 2
l = -10

since a length cannot be negative, this root is not viable. therefore l = 7

to solve for w you would use

w = l + 3
w = 7 + 3
w = 10 

hope this helps! if you did not understand a step or concept please let me know!
