Error cs1519.... just need a little help is all

so im trying out coding and i have no clue how to solve this one. usually im good at fixing this but it wont fix bc its at a line i did nothing too.

its at (9,12) and its an unexpected symbol ‘void’ in class, struct, or interface member declaration.

using UnityEngine;
using System.Collections;

public class BulletG : MonoBehaviour {
		
	float lifespan = 3.0f

	// Use this for initialization
	void Start () {

	}

	// Update is called once per frame
	void Update () {
		lifespan -= Time.deltaTime;

		if(lifespan <= 0){
			Explode();
		}
	
	}
	void OnCollisionEnter() {
		//Destroy(gameObject);
	}
	void Explode() {
		Destroy(gameObject);
	}
}

Line: 6, you’re missing a semi colon at the end of the variable lifespan.

specifically change this:

 float lifespan = 3.0f

to

 float lifespan = 3.0f;

without the semi colon the declaration is not terminated and continues down the lines, so void is confusing to the compiler. However with a semi-colon, when it hits void it doesn’t interpret it as part of the field declaration of lifespan.

Line 6 is missing a semi colon:

float lifespan = 3.0f;
