Answer:
1. x = - 1 -y over 2
2. x = -4(2+y) over 3
Step-by-step explanation:
Ten times two is equal to twenty.
7x9=63
63÷2= 31.5x4
126= area of the triangles
7x7= 49= area of the square.
126+49= 175 ft
Answer: 2. please brainliest
Step-by-step explanation:
Answer:
To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don't have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.
Step-by-step explanation:
To find the volume of a soccer ball,the formula is V=4/3 πr^3,where r is the radius and π=3.14. A regulation soccer ball has a radius of 35cm. find the volume of a soccer ball to the nearest cubic centimeter. This is just some to keep in mind.
