Answer:
V=1884 Cubic mm
Step-by-step explanation:
We know that the volume of the Sphere is given by the formula
![V= \pi r^2h](https://tex.z-dn.net/?f=V%3D%20%5Cpi%20r%5E2h)
Where r is the radius and h is the height of the cylinder
We are asked to determine the radius of the hollow cylinder , which will be the difference of the solid cylinder and the cylinder being carved out.
![V=V_1-V_2](https://tex.z-dn.net/?f=V%3DV_1-V_2)
![V=\pi r_1^2 \times h-\pi r_2^2 \times h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r_1%5E2%20%5Ctimes%20h-%5Cpi%20r_2%5E2%20%5Ctimes%20h)
![V=\pi \times h \times (r_1^2-r_2^2)](https://tex.z-dn.net/?f=V%3D%5Cpi%20%5Ctimes%20h%20%5Ctimes%20%28r_1%5E2-r_2%5E2%29)
Where
is the the volume of solid cylinder with radius
and height h
is the volume of the cylinder being carved out with radius
and height h
where
mm ( Half of the bigger diameter )
mm ( Half of the inner diameter )
mm
Putting these values in the formula for V we get
![V=\pi \times 25\times (7^2-5^2)](https://tex.z-dn.net/?f=V%3D%5Cpi%20%5Ctimes%2025%5Ctimes%20%287%5E2-5%5E2%29)
![V=3.14 \times 25 \times(49-25)](https://tex.z-dn.net/?f=V%3D3.14%20%5Ctimes%2025%20%5Ctimes%2849-25%29)
![V=3.14 \times 25 \times 24](https://tex.z-dn.net/?f=V%3D3.14%20%5Ctimes%2025%20%5Ctimes%2024)
![V= 1884](https://tex.z-dn.net/?f=V%3D%201884)
Positive if I looked at graph correctly
Answer: 31 is a prime number because only 1 times itself equals 31. no other two factors equal 31 as a product.
Step-by-step explanation:
The measure of m∠J=90°, m∠G=55° and m∠H=35°
Step-by-step explanation:
Inscribed angles subtended by a diameter are right angles. Hence angle GJH =90°
The diameter GH and chord GJ intercepts an arc with a measure of 70°.The measure of an arc of a circle is equal to the measure of the central angle that intercepts the arc. Hence angle GOJ=70°. Radius of circle GO=OJ, which means triangle GOJ is an isosceles triangle thus ∠OJG=∠OGJ =(180° -70°) /2 = 55°. m∠G=55°
m∠H = (180°-(90°+55°) ) = 180° - 145° =35°
