1 answer:

horsena [70]3 years ago

8 0

Step-by-step explanation:

3 balloons + 2 cakes = £19

=> 9 balloons + 6 cakes = £57 (multiply by 3)

9 balloons + 6 cakes = £57

- (9 balloons + 3 cakes = £42)

=> 3 cakes = £15, 1 cake = £5.

Therefore 3 balloons + 2(£5) = £19,

3 balloons = £9, 1 balloon = £3.

Hence each balloon is £3 and each cake is £5.

Volume of right trapezoid cylindar whole bases are B 16m, b 8m, height is 4m and length is 32m

viktelen [127]

Answer:

$volume = 1536 m^3$

Step-by-step explanation:

given data;

B = 16m

b =8 m

height H = 4 m

length L = 32 m

volume of any right cylinder = (Area of bottom) \times (length)

Volume = A* L

The area of a trapezoid is

$A=\frac{1}{2} H*(b+B)$

$A =\frac{1}{2} 4*(8+16)$

$A = 48 m^2$

therefore volume is given as

volume = 48*32

$volume = 1536 m^3$
