Answer:
The volume of a sphere:
or
(Rounded to the nearest hundredth if needed)
Step-by-step explanation:
-To find the volume of sphere, you need this formula to help you solve the problem:
-Use the given radius 
for the formula:
-Then, you solve:
-Round up to the nearest hundredth if needed:
Answer:
you have to do, x axis times y axis which should give you your answer.
Step-by-step explanation:
The angles and lengths of each of the given triangles are;
5) m∠B = 57.52°
6) B = 70.81°
7) AB = 55.43 Km
8) AC = 39.06 ft
<h3>How to use cosine rule?</h3>
The cosine rule is expressed as;
c = √[a² + b² - 2ab(cos C)]
5) Using cosine rule;
BC = √[21² + 13² - 2(21*13)(cos 91)]
BC = 24.89
Using sine rule, we can find angle B as;
21/sin m∠B = 24.89/sin 91
sin m∠B = (21 * sin 91)/24.89
sin m∠B = 0.8436
m∠B = sin⁻¹0.8436
m∠B = 57.52°
6) Using cosine rule;
14² = 11² + 13² - 2(11*13)(cos B)]
196 = 121 + 169 - 286(cos B)
cos B = (121 + 169 - 196)/286
cos B = 0.3287
B = cos⁻¹0.3287
B = 70.81°
7) Using cosine rule;
AB = √[24² + 36² - 2(24*36)(cos 134)]
AB = 55.43 Km
8) Using cosine rule;
AC = √[21² + 26² - 2(21*26)(cos 112)]
AC = 39.06 ft

Answer:
it would be about 63.44..
Step-by-step explanation:
you can do 230/87=24/x where x is the new height, when you cross multiply and divide, x should be about 63
