Answer:
Step-by-step explanation:
Recall that the volume of a whole sphere is given by the formula:
then, the volume of a semi-sphere would be half of the formula above:
Now, the radius R is given by half of the semi-sphere diameter: 15/2 = 7.5 cm.
which makes our calculation:
what i got was 490 what i did was first i did 40 times 6 then i added 250 and got 490
Answer:$20
Step-by-step explanation: We first need to figure out how much a single candy is worth. To do that we need to divide 40 candy bars by $30. 40/30 is equal to 4/3 or $1.33 dollars each. Now we multiply 15 by the price of a single candy bar which is 4/3 or 1.33 dollars. 4/3*15 is $20.
Answer:
The largest side is OP.
Step-by-step explanation:
ΔNOP, m∠N = 110° and m∠O = 38°
According to he property of the triangle, the sum of all the angles of the triangle is 180°,
So,
m∠N + m∠O + m∠P = 180°
110° + 38° + m∠P = 180°
m∠P = 32°
The side opposite to the largest angle is largest.
Here the largest angle is m∠N so the largest side is OP.
