Answer:
45
Step-by-step explanation:
9x60=540
540/12= 45
(3/4)*(24)= 18
(3/4)*(36)= 27
The new dimensions are 18 cm x 27 cm
Answer:
Option D. 5890.5 feet²
Step-by-step explanation:
An individual head of a sprinkler system covers a circular are of grass with a radius of 25 feet.
Yard has three sprinkler heads that each cover circular area with no overlap.
We have to calculate the approximate area watered by these 3 sprinkler heads.
Area covered by one sprinkler = π×r² = π×(25)² = 625π feet²
Therefore area covered by three sprinkler heads = 3 × 625π = 5892.85 feet²
which matches the approximate value of Option D. 5890.5 feet²
What is the number of the base is it 1 or 10?
