A cylindrical tank contains 172.48 litres of water. If its height is 0.7 m then find the radius of the base.

Radius= 8.86 m

Step-by-step explanation:

Pie x r^2 x 0.7= 172.48

Pie x r^2= 246.4

r^2= 78.43

R= square root of 78.43

Radius= 8.86m

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
