The angles opposite the congruent sides of an isosceles triangle are congruent find the value of x in the triangle

2 answers:

7 0

Base angle + base angle + 70degrees = x degrees
x + x + 70 degrees = x degrees
2x + 70 = x
2x = 70 - x
2x = 60
x = 70.2
x = 35

Work out the volume of the solid shape Give your answers in terms of pi please

kirill [66]

*The complete question is in the picture attached below.

Answer:

756πcm³

Step-by-step Explanation:

The volume of the solid shape = volume of cone + volume of the hemisphere.

==> 270πcm³ + ½(4/3*π*r³)

To calculate the volume of the hemisphere, we need to get the radius of the hemisphere = the radius of the cone.

Since volume of cone = 270πcm³, we can find r using the formula for the volume of cone.

==> Volume of cone = ⅓πr²h

⅓*π*r²*10 = 270π

⅓*10*r²(π) = 270 (π)

10/3 * r² = 270

r² = 270 * ³/10

r² = 81

r = √81

r = 9 cm

Thus, volume of hemisphere = ½(4/3*π*r³)

==> Volume of hemisphere = ½(⁴/3 * π * 9³)

= ½(972π)

Volume of hemisphere = 486πcm³

Volume of the solid shape

= volume of cone + volume of the hemisphere.

==> 270πcm³ + 486πcm³

= 756πcm³

What are equivilant equations?how do you find them?

TEA [102]

Answer:

Equivalent equations are algebraic equations that have identical solutions or roots. you can find it by adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation as well as multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
