Step-by-step explanation:
Answer:
154
Step-by-step explanation:
The formula for the area is A=πr2
The line labeled 7 is the radium or the R in the formula
Replace 7 with R
A=π7(squared)
square seven
A=49π
pi is approximately 3.14
mutiply 7 by pi
A= 154
Answer: 20 feet
Step-by-step explanation:
This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.
Solve with Pythagoras rule:
c² = a² + b²
c = hypotenuse
a= length
b = height
29² = 21² + b²
841 = 441 + b²
b² = 841 - 441
b² = 400
b = √400
b = 20 feet
