Answer:
r = 7.1 cm
Step-by-step explanation:
Given the following data;
Volume of hemisphere = 757 cm³
To find the radius of the hemisphere;
Mathematically, the volume of a hemisphere is given by the formula;
Volume of hemisphere = ⅔πr³
Where, r is the radius of the hemisphere.
π = 22/7
Substituting into the formula, we have;
757 = ⅔πr³
Cross-multiplying, we have;
757 * 3 = 2πr³
2271 = 2*22/7*r³
2271 = 44/7*r³
Cross-multiplying, we have;
2271 * 7 = 44r³
15897 = 44r³
r³ = 15897/44
r³ = 361.30
Taking the cube root of both sides, we have;
r = 7.1223
To the nearest tenth of a centimeter;
r = 7.1 cm
Answer:
The answer is 15
Step-by-step explanation:
You just have to multiply angle BC times angle AC to have the answer because angle AB is verticle to angle BD.
All 3 of these would result in the same answer. You can see this by looking at the cross products that would be created for each of them.
In each proportion, you would get a variation of 37 times 7 = 4 times x, when you multiply the numerator of the first by the denominator of the second and the denominator of the first by the numerator of the second.
Step-by-step explanation:
<h3>Answer:</h3>

3 from the numerator was multiplied six times, and 3 from the denominator is multiplied 4 times. The small number at the top right (which is the exponent) of the 3 is how much the number is repeated.
