For problem number 4!!

Step-by-step explanation:

we have to find the base area of a cone whose curved surface =25 m

height of cone=20 m

radius of base=√(25²-20²)=√(625-400)=√(225)=15 m

so base area=πr²=π×15²=225π≈706.86 m²

could you reply to this with the question so i can ?

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
