spin [16.1K]3 years ago
5 0

Answer:

approximately 10

Step-by-step explanation:

Volume = 1/3h times \pi times radius square

1570 = 1/3 x 15 x 22/7 x r^{2}

1570 = 5 times \frac{22}{7} times r^{2}

1570 = 15.71r^{2}

\frac{1570}{15.71} = \frac{15.71 r^{2}}{15.71}

99.9 = r^2

\sqrt{99.9} = r

≅10

Given that a=16cm and b=17cm work out the height of the triangle
lilavasa [31]

Answer:

√33 cm

Step-by-step explanation:

Here,

b² = a² + c²

Because it is a right triangle

=> (17)² = (16)² + c²

=> 289 = 256 + c²

=> 289 - 256 = c²

=> 33 = c²

=> √33 = c

Hence,

height of triangle is √33 cm
