Answer:
of a house per day
Step-by-step explanation:
A rate is simply the measure of of one quantity against another quantity.
Here, we are simply to measure the number of houses the team of painters can paint against the number of days they spend painting them.
Simply put, we need to find the number of houses they can paint in a day.
To do this, all we have to do is divide the number of houses painted by the number of days they spent painting them.
They painted 3/4 of a house in 4 days. Therefore, the rate will be:
of a house per day.
They are painting at a rate of of a house per day.
Solution -
drawing a perpendicular from AQ to TS, we get a right angle triangle AQT
Using Pythagoras Theorem,
AT² = AQ² + QT²
⇒26² = 24² + QT² (∵ Due to symmetry AQ = RS)
⇒QT² = 676-576 = 100
⇒QT = 10
As TS = QT + QS = 12 + 10 = 22 ( ∵ Due to symmetry AR = QS )
∴ TS = 22 (ans)
Answer:
Step-by-step explanation:
Given
Shape: Right Circular cone
Height, h = 12.5 cm
Base circumference, C = 5.8cm
Required:
Calculate Volume
The volume of a cone is calculated as thus;
Volume,
Where V, r and h represent the volume, the radius and the height of the cone respectively
But first we need to calculate the radius of the cone.
Using formula of circumference.
We have C to be 5.8cm
By substituting this value;
Divide through by
Now, we can calculate the volume of the cone
By substituting and h = 12.5 cm;
becomes
Take as 3.14
---- Approximated
Hence, the volume of the cone is;
